Derp, I meant a whole clutch kit, not just the disc. I had a ACT 6-puck sprung on my street turbo miata many years back and I LOVED it. I might go with their full organic disc.

Thanks for the insight on the neck restraint and coupons! How does it handle 3" shoulder straps?

It is perfect for 3" shoulder straps, that is what I use with it. The little uprights near the ends keep them securely in place, I've never had an issue with them moving around on the device at all.

The reason that I like the three puck design on the Exedy is that it means the moment of inertia is much lower for the disk when compared to a 6 puck or full face. When you shift, the synchro has to overcome the stored energy in the spinning clutch disk. So in theory, lower moment of inertia disk, means less stored energy to overcome, means faster shifts and longer lasting synchros.

I saw a few of my bad habits in your driving.

I always over brake for T1. You are supposed to carry enough speed that you need to kiss the curbing on track out. But as Emilio pointed out, it is a big hill and it scrubs off some speed for you.

Don't over brake for T5. You need that momentum to climb that steep hill. And you can tell everybody here that it is much steeper IRL than it looks on the video. Just beware if someone left gravel in the paint area at track out. It does look like you are using all of track out, which is good.

T6 is actually banked and can be taken slightly faster than you think.

T7 was discussed above and you know what happened there. Faster on exit there means faster for the whole straight.

T10b is the start of a very long straight that just happens to start with a hill and a bend. As was stated above, .5 mph faster there means .5 mph faster for that whole distance to T1 braking zone.

T12. T12. I don't have the balls I once did for T12 back when I had less power. That and my buddy wadded his car up there in an incident that looked like an Olympic tumbling routine.

If you are on the bumpstops in T1, then you are on them in T12, too.

If you can afford a track day entry fee, you can afford a fire suit. If you can afford tires, you can afford a HNRS. If you can afford the food and lodging for the weekend, you can afford a harness, gloves, etc. It looks like you are one skipped event away from actually being ready for an event, lol.

+1 for NECKSGEN

:bigtu:

I'm only on the bump-stops in T1 right as I hit the bump at apex. This was only my 2nd time at RA, so I'm not sure if that bump has gotten better or worse of the past few years.

The fast SCCA guys are at Road Atlanta this weekend.

Top 6 cars have fast laps of 1:44.0, one guy ran a 1:43.8. These are race times, so probably lots of drafting down the straights.

Yeah, I'm a hack compared to most of those drivers. If Espinosa did a 44.2 in a mildly prepped TTE e30 I'm pretty confident a proper NB1 could do high 41s. Shit if I had power cap (15 more hp) I could be in the 43s with my driving.

Back from a great weekend at Roebling. Managed to win both days in a field of 9 in TTE.

Here's one of my fastest sessions on Sunday morning:


I had a few goals this event:
1. Successfully finish the instructor clinic on Friday, which I did and I learned A LOT from Sonny T.
2. Win at least one day for some contingency and year-end points.
3. Get into the 1:22s, managed that twice with a new PR of 1:22.879. I was 3-4 tenths off the track record of TTE, I'm happy with that.

Winning both days was really the cherry on top.

However, Danny Steyn and Blake Clements were both out there running in TTD(even though they're probably TTE cars) this weekend. They gave me a quick reminder of how fast I really should be going. Sure, my car needs some work and it's not a top-flight TTE car, but damn those guys can wheel. I talked to Blake some and he gave me some encouragement, which I appreciated. Then I got to follow Danny around for a couple of laps and figured out I was doing T6/T7 inefficiently. Danny actually got a 1:22.2xx on the first Sunday session. So I was basically running slightly behind/similar times to top SM cars/drivers, I'll take that for now.

And sorry I still don't have full safety gear yet! I was on a tight budget this weekend. I drove car down there, setup tent, swapped tires, ran, checked oil, ran some more, thankfully won, swapped tires back, drove it home. All in all it was a success.

Such a shame about Marcus. So young. He wasn't even going that fast when he hit the wall. HNRS would have saved him for sure. So sad. He'll be missed.

Sorry to hear someone got hurt. What is HNRS I googled but nothing showed?

A HNRS stands for Head and Neck Restraint System. A common one is a HANS.

Emilio was trying to get this guy to buy the necessary safety gear.

So something like this:

Team Valhalla Racing 360 Plus Restraint Device - SafeRacer

No more like this.

Home

Yes lets give money to the company that tries to sue other safety companies in order to keep the prices high on life saving pieces of equipment. :jerkit:

This

In my own quiet way, I boycott HANS, thus the blanket HNRS recommendation. I have two Necksgens and an Impact Accel

I was responding to someone who posted what was basically a glorified neck donut. I was just responding with an actual HNRS. Hans is what I use and what popped into my mind first.

I see what you did there! So I know this doesn't make any difference, but I haven't had a 4-off in my NASA career.

I need to run winding road stickers for contingency, but I want to support my local vendor(OG Racing). Need to holler at Johnny to talk race suits soon. I've already contacted BSI Racing on a cage over the winter too.

I didn't know they did this...... that sealed the deal for me to get a Necksgens.

I'm not trying to stir something up, but why do people use this argument? The Necksgen Rev and the HANS sport 3 are the same price...

If ANY company had patents on HNRS devices and other companies were infringing on features, they would sue the offending company. I'm not saying HANS is right for trying to corner the market on something that saves lives, but there are thousands of life saving patents that have owners that are willing to sue infringers.

That being said, I'm not sure which unit to buy out of all the offerings. They are all better than a broken neck, and are all worth the $600 pricetag for that reason alone

Yeah...

You should google what kind of dirty pool the guys at HANS have been playing.

Necksgen owner here because HANS doesn't deserve to be rewarded.

Back from another awesome weekend! This time I got to hang out with two of my best friends. We've talked about going to the track together since we were in high school, it was awesome that it finally came to fruition.

My miata, friend's TTB M3, and other friend's E30.
https://www.miataturbo.net/attachmen...ine=1463505811

This event was at CMP(Carolina Motorsports Park), fun course but the surface is worn out, low on grip, and hard on tires. I finished 1st both days, which always makes me happy:
https://www.miataturbo.net/attachmen...ine=1463505811

day 2:
https://www.miataturbo.net/attachmen...ine=1463505811


On Sunday morning I was riding with my student(my buddy in the E30) in a DE2 session right before our first TT session of that day. So I asked my other friend(M3) to start my car to let it warm up before he got into his car. Well, my starter had some solenoid issues since I finished the clutch job last weekend. The solenoid would stay engaged and keep the gear spinning with the flywheel for about 30-45 seconds, sometimes shorter, and then pop off. My friend didn't really know this and thought the car was guna catch fire or something horrible. The car would try to start unless you pulled the key out completely. So he got the car to stop making the funny noise(starter gear spinning) and quickly got in his car and went to grid. Unfortunately....... he put the key of my car in his pocket when he went to grid lol. So I missed the first session, which was undoubtedly the fastest session of the weekend. Couldn't be mad at my friend, as he just reset the TTB track record, and I didn't let him know about the weird starter issue. :rofl:

Anywayzzz, got out on track during the 2nd session and ran my fastest lap of the weekend. I had to start from the back, but traffic was pretty damn polite this heat.

Here's the fastest lap, sorry for the quality/shake I had to use the gopro1 since I forgot the microSD card for the gopro4 :facepalm: Sloppy lap, but still fun.


Next month(June) I have already budgeted to purchase a neck restraint!

I'm suppose to go to Hyperfest at ViR this weekend, but I really need to get the starter sorted out. I'll be by myself this time, so if it doesn't get sorted I might have to skip it.

Hyperfest was a shitshow when it was at Summit Point, I wonder how bad it is at VIR. Hyperfest is one event I would never goto to do real track days.

Overly crowded and such? What other details made it a shit-show?

100% of t-storms on Saturday..... and I'm camping ::td: Looking more and more like I'll skip it.

hyperfest grew too much for Summit point. it was wayyy overcrowded. VIR has about 8 times the room. i went last year (going again this week) and it was much more spread out. you could spend the entire week and not need to drive threw the drifters gypsy village.

Hyperfest is like a Friday night RiceBowl car meet x 1000. I had tons of fun as a spectator, all my friends who were there to drive over the weekend always hated it. Saturday is far worse then Sunday. I will say the rollover competition I did at Hyperfest one year was lots of fun.

Daisy Dukes, lol. Looks like they went to recruit participants at the local strip club. :giggle:


Also, this happened first hot-lap on Saturday's practice session :doh: This was on the passenger front, the corded area was on the inside.
https://www.miataturbo.net/attachmen...ine=1463576947


The other 3 tires are ok, they're at about 24 heat cycles now. I'm not sure what to do with them honestly....save the best 2 and pair them with a 2 other stickers for practice tires?

This weekend was a blast and the most fun I've ever had in TT!! Running some close times and doing some really fun sessions with other TTE/D guys. The urge for w2w is strong, but the low PTE turn-out in the SE keeps me away from it(and the entry fees/not being able to instruct). My dad also finally got to come out and run in HPDE in his GTi. Eventually he'll work his way up to TT and we'll do a team entry.

Came to this event with fresh R7s, I didn't get to scrub them in properly though. At some point, I'd like to get another set of wheels so I can scrub and cure correctly. First timed session I grid behind Espinosa in the E30 and got to run with him the whole session and holy shit does that guy haul ass. The entire session I could tell he was having fun, we did a small tandem slide out of T5(I thought we were going off tbh) and topped the hill and he was pumping his fist, it was great lol. Unfortunately we got caught behind some traffic that held us up in T6/T7 the whole session, so our overall times were slower than what they could of been. I believe the E30 had some old Toyo RRs, because there were several turns where I could close the gap between us and even hold me up. The power difference was noticeable, once we hit 95mph it's like a switch went off and the E30 walks away from me on the straights. So my draft on him during the front and back straight wasn't for too long. Lucky for me, I did something just a hair better on our first hot-lap. This Saturday session was around 10:30AM, no clouds, and already 85* or hotter.

https://www.miataturbo.net/attachmen...ine=1465220612
(Espinosa is on Team Parkhurst)


On Sunday the weather looked super sketch, 80% chance of rain(tstorms) by the end of our first session. So I figured I would have to get it done then, granted it rained during the night and it was damp out for the first DE4 session. Traffic was great, more or less an open track, some overcast and low 70s*, I felt good about it. First hot lap I get through T1 like I've been wanting to for awhile, much higher rpm in 4th than normal, still don't think I can take it in 5th. T3 felt great, used all the curb, T5 felt decent, traffic let me by coming into T6/T7, and I thought this was it! So..... I run harry's lap-timer on my phone mounted on windshield/dash, I basically only run it to look at my times across the start/finish, so if I run a good time I can end the session early. Well, I decided to look at it on the back straight and see that it's green -0.24x from my virtual best of 1:44.8xx, thinking "hell yeah, I'm guna get into the 44s!!!" I come into T10 and fuck up my downshift to 3rd, slip a little too much, finally get out of 10b, crest the hill and look again at the phone....... red +0.9xxx :vash: End up with a 1:46.0 for that session :(. Come in and see that Rensel(who drives a Sentra) ran a 1:45.2xx that session, ugh..... I lost.

Our next session is close, about 45min after finishing our 1st session. I check the weather to be pleasantly surprised that the rain will hold off! This session I don't even start the laptimer and I don't have much to lose.... I was already happy about winning on Saturday. Espinosa hops behind me, Rensel is a couple of cars up. Thankfully, traffic played really nice and I was able to get some clean laps in. By the end of lap 2 I could tell I was reeling the Sentra in(from t1-t7 anyways). With a rabbit to chase I pushed pretty damn hard and by T7 of lap 3 I was right behind the Sentra. Once we hit about 75-80mph he starts to pull away, by the time I'm at 95-100mph, he's 8-10 cars away, so I guess I caught some of his draft at least until 90mph maybe? We do another lap front-to-back and it was a blast, Rensel gets the most air-time I've ever seen on T3. It honestly looked like his whole passenger's side was 2+ ft in the air, lol.

Come off track, go get a weight because I'm sure that was my last session. I actually weigh in at 2433, a solid 20lbs over weight, go figure. Talk to Rensel about how much fun that session was, he tells me his timer had a 1:44.5xx. I thought "oh there's no way I went faster than that, I think I might of been a 1:45.0-flat". Shoot the shit some more with him, then I head back to my spot. Asked my friend if he checked the results, see if either of us went any faster, then tells me "ohhh 44.2" ...... "holy shit that's my time?!". Best feeling in the world running way faster than you ever thought. I love having a rabbit to chase!

The rest of the day turned out really nice, it didn't rain at all. I was able to give Don (CurlyDE on here?) a ride during an afternoon DE4 session as well. Unfortunately I didn't have the gopro4, so I had to use the gopro1 which has a bad mount and dies quickly. I think got the session of Espinosa and I, but I'll have to double check the video later today.

In Miatas, 6whp is enough to break a single car draft. Seeing as the Sentra should have at least 20whp on you despite punching a bigger hole in the wind, its still no surprise he dropped you so easily.

sorry if i held you up. i was on the mosler on Sunday. with the car not being done, i had to borrow a vehicle to get some ttu points.

Yet another example of a vendor trying to keep a normal member down. :giggle::giggle:

I'm not too familiar with drafts, care to get the spoon out? :D At what average distance would I stop gaining from a draft? Or is that a broad question...... lol

Naw man, I never even saw ya! It was a TTB car that held us up in T6/T7, doing sub 50mph in T7, which completely killed our laps :(. I do need to sign up for that instructor thing though..... will e-mail you tonight.

For the record when i keep people down i use super rare 1980's race cars.

https://www.miataturbo.net/attachmen...ine=1465239786



it was a load of fun and i was very slow in it. something about a 20 year old 2.2L turbo Chrysler engine doesn't equate to speed.

Primer: Drafting 101

Thanks! I think I've read this before, years ago though.

Snagged a used one! Seller said he used it about 3 times.https://www.miataturbo.net/attachmen...ine=1466383549

Long time, no update. Soooooo this will be long-winded......


Went down to Barber Halloween weekend, which is an amazing facility and track. 10/10 would recommend. My friend and I decided to do a team-entry since his TTB M3 was down and I was unsure on how my performance would be since this would be the first time back out on track after slamming my Z into the wall at Road Atlanta. So it all worked out.

In the middle of last week I noticed only 4 in TTE and 5 in TTD, so I decided to bump on up for a chance at contingency. Didn't really change anything on my car for TTD, I just didn't have to worry about weight. In my 2410lb car that usually means make sure I have 1/4 tank or ~2.5gals for impound.

Here's one way of doing it...... TONS of mistakes I know. I was also being really conservative in several spots. This was my morning session on Sunday with a 1:47.2xx. My afternoon session I built up more confidence and ran a 47.8xx in the heat of the day. I assume a soft TTE record of 1:46.7 since I wasn't far off and I didn't drive that well.



Then here's the correct way....James running a blistering fast 1:43.9xx Sunday morning. The TTD record is a 1:43.5xx. The car weighed around 2380lbs +/- 5lbs when he ran this session, 12th heat-cycle on this set of R7s



It was painfully apparent that I need stiffer springs, currently on 700/400 still. It would of been pretty beneficial not being on the bump-stops through several high load turns at this track. Scratch that, turns out my shocks are really worn out.....

Looking down into the shock body with the shaft/piston removed. Those scoring rings are not supposed to be there :(
Attachment 233955
Attachment 233956
and the piston with a dirt build-up on the seals
Attachment 233957

So after talking to John(Wag) @ Inertia Laboratory about my options I decided to buy new shocks. I was very tempted to go with gen2 Xidas, but I found some bnib 5100s for a good price, so I'm snatching those up real quick. I also learned, 5100s received their valving from the Xida development.... So 5100s are actually gen 1 Xidas? hah

During the removal of the shocks the bottom bolt on of the rear shocks was being stubborn. On NB control arms they have a nut within the LCA..... one would probably think it's tack welded onto the LCA or something, right? Well it's actually just a captive box with very thin metal keeping the nut in place. I suppose mine have been hit with an impact one too many times. Had a friend cut a window in the LCA, tack weld a nut(without coating) to the LCA, weld window back, re-paint, good to go.
Attachment 233958


While removing the UCAs to install some delrin off-set bushings I determined my ball-joints and outer tie-rod ends were too floppy. So I've ordered new upper and lower balljoints(OEM design because NASA points) and outer tie-rod ends. With the new shocks, more camber up front, then a higher ride-height, and new ball-joints the car should feel and drive better. Though, it drove pretty good before hand too.

Got some other bits over the winter for the car, ARP wheel-studs, wilwood prop valve, TSE brake ducts(2" design because it was a good deal from a friend) with some hi-temp hose and inlet flanges from aircraftspruce.
Attachment 233959

With the Z totaled from the wreck at Road Atlanta that opened the opportunity to finally buy a tow vehicle! I ended up with with a 2008.5 Nissan Titan, 80k mi, 2wd, w/ tow package, no rust all for a decent price. Besides the gas mileage it's been great, haven't got a chance to tow with it yet, maybe in a couple of months when season starts back up and I have my car back together.

Attachment 233960

more to come later!

Bye bye 9" wheels.

Are you saying that based on points and rules, or saying 9" wheels won't fit with delrin off-set bushings?

Yeah, I think I'm guna have to run some 5mm spacers.

They wont fit when using offset FUCA bushings. Offset LCA bushings allow them tofit.

I have 15x9 Gen2 6UL's on my car with the sadfab offset bushing, along with the EBJ and the wheels fit fine and I have not had any hitting issues so far. I do only have about 150 miles on it all though.

You have offset lower control arm bushings

​​​​​​​I missed the UCA part, my bad, ignore my rambling.

Depending on the 2018 ST5/6 rules I'll probably do to ELBJs and swap non-offsets back into the UCAs. Until then, or if they don't allow ELBJs, I'll just run a 5mm spacer.


Got sum new shoez, new gloves, and a new helmet. Currently eye-balling a Sparco RS-4 suit and a OMP HTE-R400 for a new seat. I'd REALLY to get the cage in the car and do the comp school in April, but it's looking like it'll be the next available comp school for me, which is in September.

So the title of this thread is somewhat accurate....unfortunately. Though, replace tire walls with CONCRETE walls. Ran out of talent and tire at Road Atlanta in the Z, smashed into a concrete barrier.
Attachment 233954

I'm still surprised I ran into a concrete barrier instead of an actual tire wall. I have a little written letter to send off to whomever at Road Atlanta to suggest moving some of the barriers back a tad and adding tire-walls. I'm thinking about filtering it through my local NASA Regional director to get their input and have them "submit" it. I actually got really really lucky with my wreck..... DALE DIED FROM LESS! I just don't understand why they're can't be more tire-walls. Keep in mind this was in T4 on the outside of the track just before the esses, so the barrier is not permanent like the front straight. Someone else wrecked in the same spot the next morning too, oddly enough. Alright, done with my rant on that.

You hit the wall doing over 150-160mph? That's what Dale Earnhardt's estimated speed at impact. That's haulin' ass in turn 4.

Style points for quoting the entire post.

Money, apathy, (in)effectiveness. Road Atlanta is old and poor compared to places like Circuit of the Americas or The Thermal Club.

forgot the /s tag, so sorry.

I could have sworn I edited down the quote before I posted it (because it annoys me when someone does the same thing), but I was pretty tired last week.

just a quick FYI his speed was 150mph-ish. his velocity to the wall was was only 35mph.

Cats for Snapping a picture of your crashed car in front of the car i crashed a few months before.

Hah, I think Matt and Rob were having weird issues with that civic that weekend.

Welp, got the offset bushings in. In hindsight, I should of just gone with the offset in the LCA. I was already committed to the UCA offsets and honestly I don't think I'll run this setup too long.....maybe just this season, ST5/6 rules pending?

New shocks come in tomorrow, so I'll start piecing them together tomorrow night. Along with snapping a few pictures of the current progress, because let's be honest...... you're just scrolling through my build and looking at the pictures. :rofl:

I am loving this thread, entertaining and informative. Do you plan on replacing the Z?

Thanks!

I bought that Titan a few posts back "to replace" the Z.

Worked on some shiny bits last night!

Attachment 233949

I ended up cutting the new rear bump-stops instead of reusing the old. New thrust needle bearings too! This new setup should be pretty compliant, really looking forward to it!

Attachment 233950


And since I'm an idiot, I ran into a road-block. When I aligned these bushings I didn't do it with the sleeves :vash: So one arm is slightly off and the other is completely off.

Attachment 233951

Attachment 233952

Going out of town this weekend, so I'm dropping these UCAs off with a buddy of mine that is going to get the damn things lined up. Definitely should of gone the LCA offset bushing route, ah well live.learn.


First event of the year for me is Feb 11/12 at CMP, so I'm trying to give myself as much time as possible to make sure the car is sorted well before it. I'll be running on the set of Hoosiers I broke in at Road Atlanta back in June and did the Barber event with, so they have about 12-14 heat-cycles. I'll bring a set of stickers to potentially mount up if the weather plays nice. Between the new shocks, higher spring rate, more front camber, and moving weight around in the car I should be able to improve on my PB there which was a - 1:51.9xx and happens to be done with 24+ heat-cycle/corded set. Current TTE record is 1:49.8 done by an e30, so I could be able to reset that :party:............ maybe

Soo all those little maintenance items that you've probably heard about on various forums, but you haven't seen first hand so there's no way it could happen to you and all that talk is just paranoia? Well....... it actually happens:
Attachment 233947

Thankfully, a buddy of mine has some spares.


Also, I've given up on the UCA offsets. LCA offsets are enroute. I've used a super complicated bushing removal method that involves some dikes and a gear puller, nawhaimsayin'
Attachment 233948

hallelujah

:rofl:

Seriously though...... UCA off-sets, never again. These LCA off-sets are easier to deal with.

Attachment 233945


Getting it aligned tomorrow afternoon and double checking torque on several nuts/bolts. Then I plan to flush out the torsen, the denatured alcohol > ATF > new synthetic diff fluid method. I've never tried it so I'll report back here with results, hopefully with positive results.

New DTC50s going on the car, I'll bed them in sometime this week before CMP. I get a little anxious bedding pads with cold Hoosiers :greddy: Unfortunately I didn't give myself enough time to install the prop valve, should have it installed before next event at RA. I'll also work on finishing the brake ducts before then.


New part for the truck! One of Dan's bookface posts reminded me to get this thing. I can't begin to describe how nice it will be to NOT have to drive the car home after an event :rofl:
Attachment 233946


There's 5 signed up for CMP, so wish me luck!

Wut? Is this supposed to restore the Torsen back to new? Sounds like an old Spec Miata trick or something.

What's that flush supposed to accomplish? I see it as an easy way to flush all of the lubricant out of the bearings, which would make me really question doing this. Let's just hope the bearings get the proper lubrication before you take it for a spin.

I've heard it a few times, seems like an older SM rumor. I have no data to back any of that up, lol.

Most likely what will happen is this: *Wednesday night* "OH SHIT I forgot about the diff, I'll just put new fluid in it real quick since I already have it here."
