Well that's a no brainer then.

SadFab front lower offsets to achieve the same as ELBJ with no points, then you can do sways and brakes. Have your cake and eat it too. Would likely win at regional level but not nationals depending on who shows up.

Championship motor came out on Sunday. Was then promptly swapped right into Emilio's temporary SPM S2 car today.

My old dyno reclass motor is 'prepped' for reinstall. I wiped parts of it down with a dirty shop rag. That'll do.

List of near-future mods/cleanup:
Proportioning valve
More cage padding
Delete blower motor and heater core
Delete OEM dash bar, mount steering column with fancy roll cage clampy thing
Finish Singular louvers
Install handmedown airdam
Build(trace/copy) undertray
Buy/build rear spoiler


Longshot:
Delete OEM ignition switch/wiper stalk thing, install Longacre starter panel
Paint interior
Prep/build spare motor for something cool


First 2017 event is Jan 28-29 at Buttonwillow. Depending on my LSD legality, I may run SPM S2, or just load a high power map, drop the ballast and terrorize the DE.

Welp, I got the motor swap completed and hauled it to the dyno. Had some trouble with fueling and decided to bail on the Supermiata race this weekend.

It is hitting 100%DC at ~6400rpm and spiking lean immediately. I am going to send the injectors off for cleaning (124K OEM) and throw another filter at it for good measure. It has a gauge on the fuel rail, and holds 59psi through to 7krpm on a fresh Walbro and clean sock, all new in October before WSC.
Makes ~141whp at 6400 on the map from the WSC zero point longblock. Should be pretty healthy when it gets enough fuel and a proper tune.

I also got 3 of the 5 piece Singular hood louvers in.

Even with narrowing the NB layout, I was able to keep some of the "A frame" bracing. So hopefully, it won't be too flappy.

Hey Dan - Can you show a picture of how you mounted your spot mirror? I am trying to figure out how to mount one before I buy it. As you know Mark didn't give us very much room to attach to the A pillar (a blessing and curse).

It is currently bolted onto the remnants of the forward A window frame. The A window itself, and the vertical pillar have been removed.
When I cut off the rest of the A window frame off for safety/convenience and egress, it'll get bolted to the similar pinch weld of the windshield.

(Car is in the trailer right now. no special pic, sorry.)

Best view of it is actually in my video: /shamelessplug

Thanks for explaining it. That video was actually the still shot I was looking at before posting. That's where I am planning to mount it too.

Appreciate the help.

Yep, folks pay a lot of money for $45 a piece cage mounted mirrors when <$10 options bolt to A-pillars.

I didn't even have the WR money, I just blindly bought two $45 mirrors. Don't get me started on the Advanced Autosports Allview clone rearview mirrors that we blew another $160 for a pair. One born every day.

4.3 Torsen acquired and installed, 4.77 Giken sold.
Prop valve installed.
brakes bled.
Sonny helped me get the car set up for SPM S2 and TT/PT double dipping with a more general (and symmetrical) alignment and corner weight. We removed a 3% wedge and .6* camber stagger from the Western States Championship effort.



Took it to the dyno Wednesday last week in effort to run Supermiata @ Chuckwalla. Lack-of-fueling problems persisted. We're all kind of stumped.
Freshly rebuilt injectors were still not enough fuel, so I am weighing my options and second guessing entire racecar motivations, NASA vs SPM, cost vs reward, #allofit.

Regardless, that meant I missed the race action. We threw together a last minute plan for me to show up in the ND and at least give DE ridealongs on Saturday in the 949Racing//Supermiata ND. So at 3:30am saturday morning I went in to the shop, pushed 3 cars in and out to make room to change wheels. Then made the 3 hour drive out to Chuckwalla on RC1s and roofless. #OnlyInSocal

I had a blast following the SPM S2 drivers around in the early sessions while trying to learn the track. Following Emilio, Sonny and Adam was highly beneficial. Chuckwalla is freaking awesome. The dropzone into the banked bowl complex of T11/12/13 is SO much fun.







In other news, and also complicating the the "what to do with Button" debate is this:


We bought this 2004 Land Cruiser as a multi purpose Wife daily/National Park exploring/camping/racecar tow rig. I bought enough trailer to be right on the tow capacity, but the '04 refresh adds a 5spd to the already overbuilt, large trans cooler, rig. It's done a couple test tows, the longest one up and over the toll road to the dyno, and did very well on temperatures. Brakes are awesome, suspension sag isn't absurd. Working well so far.



I won't see a track until April 8th with RoadsterCup. Hopefully in my own damn car this time...

I realize it can be discouraging when the car doesn't come together correctly before an event, been there, got the t-shirt. But what else would you do with the car besides S2 and potentially dip in NASA PT/TT?

Dan is continually torn between the, still new to him, excitement of participating in a national series with coastal championships, free tires and lap records (NASA) vs better quality racing, lower overall costs, more camaraderie but no national or coastal championships, fewer free tires (Supermiata).
Only really has time and budget for one and just barely at that. So trying to plan a build to switch back and forth is untenable in my view.

Most of us in Socal that ran with NASA PT in Miatas in recent years kind of got burned out by the politics and expense. Dan hasn't reached that point yet. Sonny and I are patiently waiting for him to concede the decision

Exactly.

"With all due respect" , NASA SoCal has pretty minimal competition and small fields. I raced against them all at WSC. My home region, Great Lakes, had 13 cars in PTE and the top ~6 all went under my '16 track record last weekend. I won't find that here, so the NASA motivation is purely to snag a lap record or two before the class goes away in 2018. 2017 WSC at Thunderhill sounds fun, but isn't in ink on my schedule. I'm doing a GL PTE race in our new Midwest Miata Parts NB1 in August for my birthday, and will only need 2 additional events out here to qualify for WSC. One trip to T-Hill to scout and one local trip to buttonwillow or somewhere sounds plausible.

Supermiata is a fun, wonderful, fantastic destination series, but I feel like i'm ending up there by default. That's an interesting motivational/emotional hurdle combined with the move/homesickness/nostalgia.

+ spares/fuel/2100lb miata.

Weight seems to be a non-issue. The big penalty is the aero drag, so California's 55mph towing law ends up being a benefit.

Welp, I guess having a hard time deciding where to devote your time between multiple fun things to do is better than having no choices! I guess it depends on where you want to end up as a driver. All signs are pointing to SPM if you're wanting to grow the most as driver.

This might be an atypical response on this thread, but if you're interested in tight competition there's always auto-x! I'm sure you're familiar with this, but some classes(SSR, CSP, etc) are stacked with talent. That's auto-x's biggest allure, IMO.

I used to autox a good amount. After doing track day's I can't go back. At least not unless it is within 30 minutes of my house and I just want fun runs. The cost of using a whole Saturday or Sunday to drive for 5 minutes just does not work for me any more.

The car is still having trouble in the power development department, but it's starting to look like a Supermiata!


Blackbird Fabworx Black Edition spoiler.
Cool new finish option for the same ultra effective, bolt on and go spoiler that we all should know and love. I could have fabbed a DiY version like some other SPMers have, but my free time is limited and valuable. I have much higher priorities when I can carve out garage time. (I owe Moti some fancy shots once I get the car Button'd up and cleaned, so I am leaving the protective plastic on as long as possible.) #doyouseewhatididthere

Singular Motorsports NA/NB louvers + Universal louvers. AKA their Maximum Attack package, or the 5 Piece Bro-nugget meal.
Honestly, these are just cool looking. We sell the middle three piece kit, but I love the look the 5pc kit on Sean's car. I've wanted to put it on my last 3 track cars. Now I have it. Install is a PITA, but I have documented most of it already, so there's no "in progress" pics.

New-to-me PCI seat mount replaced my Memoryfab UltraLow locking sliders. Stiffer, lower, more leg and elbow room. I can also add the butt pad back in without hitting my head on the cage. Win/win/win.
My Sparco Evo is narrower than the Sparco Sprint this bracket was designed for, so it needed 5mm spacers on the front holes and 10mm spacers on the rear holes. The Evo bottom is flat/square so cutting the cross bar out would not gain any room to lower the seat. As it is, the seat nearly rests on the bolt heads on the rear mounting humps. Nothing to be gained without going 100% custom. This is a very legit bolt in combination.

DIY plywood undertray and a spare NA airdam to mock up with. (Airdam doesn't fit perfectly, as seen in above photo)
Plywood because this large undertray actually produces downforce and needs to withstand that. This is also a car that goes farming quite often and needs to stand up to that. I can hang from it @ 190lbs. Schwing.

Removed the OEM dash bar, blower motor, etc.
This was a huge job. My cage is welded in/around/behind the OEM dash bar because I opted to keep it SpecMiata legal for resale potential. I have moved past that consideration and now value the cleanliness and light weight of a cage-only dash bar. So I had to cut my oem dash bar into three pieces to remove it from around the cage's dash bar. Excuse the wiring mess for now.

I'll be using this Sweet MFG circle track steering column clamp to attach the OEM column to the dash bar. This will require deleting the combo switch and ignition cyl, which will require a super cool new racecar starter panel. Yay, more parts shopping!

I also cut the A pillar death spikes off the doors, and remounted the driver's side spot mirror directly to the windshield frame.
Pros:
Less chance of stabbing us when working on car with door open, dyno, loading enclosed trailer, etc..
Easier egress whether the door is open or closed, safer.
Lighter.
Con:
Can't bolt the window guide back in for weatherproof storage, but this is SoCal...

This aero package can still fit into PT.
If I run in E, I will have to run a dyno reclass because of the cylinder head. That gives me the option of using an asterisk to pay for the 3pt airdam and 4pt spoiler (asterisks are 7pts).
If I run in D, I have the option of a few different reclass setups or a straight points build.
