Just to give some insight/sneak peek at why we've just introduced the DynaPro 4 upgrade option for existing front kits... There's going to be even more reasons to switch to the DP4 soon as well.

Working with Wilwood on a custom DynaPro 4 for the rear of the car that matches the bias we want with correct piston size back there, but will take the same 7812 pad as the front. This will solve the issues we run into where the pad we want to run all around is available for nice and cheap for a front Wilwood caliper application, but the matching compound is either much more expensive or not available at all for the factory caliper in the rear.

Buy one pair of pads, it fits all four corners of the car. Oh, and rear pad life will be stupid good.

God damn you. Now I have to spend $300 on calipers AND a rear brake kit :vash:

You could rotate front to rear. Hmmmmm . . . .

Sounds like yet another thing of yours I need to buy.

Yep. You'd only need to bring one pair of spares to the track.. or if you forgot your spares and your fronts are getting low, just rotate pads front to back.

Anyways, this is the only place I've mentioned what's in the works. Carry on, just thought current caliper decisions being made might want to take that into consideration ;)

Thanks Ryan!

<p>Thanks a bunch Ryan! This is cool news.</p><p>My current plan is to try and find used dynapros. Otherwise get them through goodwin.</p><p>I won't be running this kit on the track until next season so I should have some time to wait for the rears to happen.</p>

Those were brand-new pads at the start of the weekend. I'm done with the Wilwood compounds for the track, I think.

I've been looking at fitting dyanlites on the rear with some of the standalone mechanical parking brakes, don't know how nobody's done this yet.

https://www.miataturbo.net/attachmen...ine=1440015667

My plan was moving dynalites to the rear, then buying dynapros for the front. I'll be making a m-tuned-esque-iesh bracket for fitting the 10.9" sport rotor under stock 1.8 caliper brackets temporally, from there making it fit the dynalite will be easy. Stupid little park brakes are as much as dynalites though, so it will be a minute, if ever...

<p>@ThePass, will the special wilwoods have a parking brake too?</p>

Unsprung weight is the main reason why not, two calipers on the back is pretty heavy.

FM has a parking-brake-enabled Powerlite caliper for the rear. It works reasonably well, you won't be doing handbrake turns with it, but it will hold the car in place. The downside is that pad availability is a bit spotty.

--Ian

That's entirely my point though, to be able to run the same pad compound f/r while still retaining a parking brake that could pivot the car should I so desire.

FWIW, I've read the powerlite has a hard time holding a parked car on an incline, not cool for a street car. Ofc I leave my shit in gear all the time, but still...

I doubt the little tiny half caliper parking brake thing really adds that much unsprung weight, either. Still has to be less than stock. Dyanpros weigh a pound more than dynalites, so dynalite + park brake < dynapro, or so I bet.

<p>I think that is added complexity that I personally don't want. 1.8 calipers on sport rotors if fine for me for now. If the goodwin solution has a parking break then fuckya bud lets do it.</p>

I have the powerlites on my car, in gear with the parking brake on is fine with the new cables. With the original cables if you tried to put it on that tightly it would pull the end off the cable.

--Ian

Snapped this just now. 0.2 lbs difference.


https://www.miataturbo.net/attachmen...ine=1440017714

Interesting, I thought I had read somewhere that dynapros were ~1lb heavier than dynalites. Are you planning on adding a simple mechanical park brake like the powerlites?

Am I wrong in thinking SCCA kinda requires an emergency brake for certain classes? Probably something else I shouldn't make assumptions on, but I thought I'd read something like that?

https://www.sff.net/people/dburkhead/prepcompare.htm

This little chart says only prepared classes can remove the e-brake, is SSM above prepared?

<p>I'm going to venture out on a limb and say that the parking brake caliper weighs more than .2 lbs....but thats just me and my silly guesses.</p>

<p>Ryan, feel free to not answer any of the questions relating to goodwins product development cycle here in public, or at all. We're happy to take it to PMs/emails if that makes you more comfortable.</p>

Nothing to be uber secretive about - Not interested in rigging up a parking brake to the rear. If you need a rear parking brake, we already have that solution (hint: our rear V4 BBK uses factory rear caliper to this day because that rear caliper has a solid/robust parking brake).

I've run without a parking brake on a street car for years without wishing for one. That doesn't mean everyone will feel the same or that it will work for every class in every form of motorsport, but there is already an option on the market with a sort-of parking brake option on a wilwood caliper, no sense in doing the same thing twice.

I'm not a fan of the Powerlite caliper in the first place, and when we began designing what we really wanted in the rear for our track cars, we had a "wish list" formed over years of tracking and went from there based around the caliper we wanted (which didn't quite exist but we're working on it), with the priorities and focus of track use at the forefront.

<p>Yep, 1.8 caliper over sport rotor seems to be my best bet. I like a parking brake too much to get rid of it.</p><p>Maybe if this becomes a more track oriented car at sometime.</p>

Have debated carrying some of these in the truck if I went that route


https://www.miataturbo.net/attachmen...ine=1440021608

Shouldn't be using the e-brake at the track with hot brakes anyways ;)

<p>Ummm, drift events duh.</p><p>Oh shit, were on mt.net. I'm fucked.</p>

The parking brake is very useful for putting the car on the trailer.

--Ian

Hids in halogens AND dorifto?

You's on thin ice!

I already kinda know the answers to this stuff, kinda, but how important is it to run the same compound pads F/R? With all the track time I get, how much longer can I expect my rear pads to last? Allofit?

Is the sport rear caliper really necessary to balance front 11.75" discs? I understand proportioning valves, but at some point you can't add any more rear bias, is this ever a problem with 1.8 calipers on sport rotors? With the sport caliper larger pistons and larger pads, would they not be balanced by the proportioning valve better?

Napa has sport calipers and brackets for $280 for a pair, $120 back to you if they'll take 1.8's as cores, so $160 for fresh calipers and brackets. You'd be able to skip the m-tuned bracket with sport calipers and brackets, right, plus the bigger pad advantage? Is pad selection for rear sports really all that bad?

Yes.

Plus, heavy rear OEM caliper is heavy. No like for maximum fast.

<p>Its horrible and expensive. Not 2 things you like for consumables.</p><p>I've been researching some mini projectors to mold into my turn signals.</p><p>I want it to be cleaner than the standard sheet of lexan in the hole with a projector behind it.</p>

15x9 has the lip start in the same plane as the wheel mounting surface. Sorry crap pic, real hard to take on black wheel.

https://www.miataturbo.net/attachmen...ine=1440029419

15x7 had the mounting surface 1-1/4" in from where the raised lip on inside of wheel starts or 1-1/4" closer to caliper.


https://www.miataturbo.net/attachmen...ine=1440029419


https://www.miataturbo.net/attachmen...ine=1440029419

I added a 1/2" spacer under my 15x7 and it still won't fit 11.5". Definitely will need 3/4" or thicker spacer on the narrower wheels.

Thanks for all the measuring relte. I was going to be surprised if the 11.5's fit the laces, but unless for some reason they have a completely different hoop design, I know they wont fit.

<p>This shit is a pain in the fucking ass. It doesn't help that my passenger frame rail is mushroomed the entire way down....so I got it half on and then just jacked up the car. Plop, it slid right into the frame rail.</p><p>Passenger side is done.

Ee ghads man, by that point it'll have annealed to the paint and the car will be literally shit.

I'd say spray undercoating on then I remembered OR doesn't salt.

I'm gonna go steam clean something....

This shell sucks. It will be condemned at some point. Just beat up in so many places.

blehhhhh

Lol @ being concerned about annealing the paint on his car.
<br />
<br />The car looks like it was painted ten years ago with spray paint by someone who didn't know what they were doing and did no prep.
<br />
<br />I like the little monster, but pretty it isn't.

<p>Hey now, its its own kind of pretty. Kind of the poor abused orphan with a good heart pretty.</p>

race car quality

<p>lolol. Most race cars are prettier than mine.</p><p>Frame rails. I'd like to leave a beaming review about how they made my car stiffer than ****, but no, cant tell the difference.</p><p>Oh well, it will offer protection during my common off road trips.</p>

Mine made a huge difference. Probably the most substantial difference of all my bracing, and i was coming from near mint stock rails...

Edit- i was really enjoying not having email notifications every 5 seconds, there goes that!

<p>Oh the car is stiffer I bet. But hell, I can't tell the difference. Lead foot and numb hands here.</p><p>Maybe I'll notice something at auto-x on sunday.</p><p>Do RS-3s normally suck when cold?

It stopped somewhere around 35 pms, but the e-mail notifications came through for three days straight. I think you broked it, lol

I spend entirely too much time on this website, can't help it, ya'll are addictive.

Grumpycat is win though, and the new posts button, I like them.

Community build thread...Aidan occasionally does the things
 

Grumpy cat is total win, and I've unsubscribed to the majority of the threads aidan likes to bump.

<p>ah shittt. wheres the fun in that. I need to start drinking again. This would be so much more fun not sober.</p>

Don't you already have a suspended license?

As of now just restricted. And that doesnt start until september 15th. Still waiting for the suspension letter.
<br />I don't drink and drive. Never have never will. If you do that you should be shot.
<br />That being said I do have 2 prior license suspensions (90 days and a year) because of MIPs (minor in posession)

I loathe alcoholics. Not a great aspiration Aidan.

<p>I don't need to go full alcoholic, some shits just better drunk.</p><p>I dealt with issues in college, but got that figured out my junior year. Actually working on my truck is what got me off alcoholic levels of drinking in the first place. It keeps me busy.</p>

Yes
Yes

:giggle:

I've mostly stopped. I drank myself into being an incorrigible beer snob to the point where I stopped enjoying beer. At this point I don't need the extra carbs/calories, plus fancy beer gets expensive. Cuts into the car budget.

<p>Need more burnouts I guess.</p>

in4vids

<p>I'll try and take some tonight. Definitely at auto-x</p>

Just pop over to Mexico real quick, you should be fine.

<p>Its more the actual filming I need to take care of.</p>
