Do the dynapro and dynalite use the same pads? I chose dynalite to get the cheapest track pads possible.

I want the orange lines anyways. #ridethe949sak

Yes, they both use the 7112 pad.

0.200" clearance on 15x7


Over 0.400" clearance on 15x9's



Inside of both wheels where you can see the humps that cause clearance issues.

Just ordered some dynalite calipers from goodwin, there's two more on ebay still but they want to charge me KS sales tax (wtf, seriously?) I save goodwin dollars for when I buy feals, maybe...

Would you be at all amicable to sharing some dimensions, Relte

Are you going to do the 11s or 11.5s?

Please share all of the drawings!

aidandj

iTrader: (5)

Sounds like relate put a bit if effort into his drawings. I'm going to take this to email for discussing intellectual property. Expect an email from me in a bit guys.

I may do 11.5", probably should just do 11" though. I need to look at the rotors closer, it should be pretty easy to make either or, if the hat has a different offset calculating the difference should be easy.

I already have 11.5" rotors for test fitting, I'm curious if they'll clear my wheels. Relte calculated the pad area about 10% higher than 11", which is about 10% more than 1.8L stock brakes, so it might be beneficial to lower pad force to keep the calipers tapering as much.

At least that's how I understand it, am I close to right?

I'll share any drawings I come up with, for sure. I need to get some pads still, then I need to find some aluminum bar stock the proper size. I imagine I can test fit this stuff super easy, don't even need to really take the miata apart.

I've also found 54mm-64mm hubcentric spacers for cheap, I'm thinking of ordering a set.

No. For what we are talking about (hard material against hard material), surface area has 0 effect on friction. Its simply: friction coefficient x normal force. Now if we were talking tires....


But more swept area means better wear, lasts longer.

On a side note, I was going through reltes thread. Youll notice a guy named "be good" who was banned by brain for suggesting that dynalites are flexy cheap calipers. Well that was johnny C, quite possibly the most knowledgeable brake guy weve ever had on this forum, who has come back under a new screen name. lmao, im glad he has thick skin.

Bigger rotors have a larger torque angle advantage, so you should have to put less hydraulic force into the brakes to get the same deceleration? Less force, less deformation, or so I was thinking. Pad area was probably the wrong wording for that.

hi_im_sean

iTrader: (3)

oh yea, definitely. I thought you were just talking pad surface area. A higher mu pad will do the same thing.

Which is one of the reasons I want dynapros.

Cool beans, if I can fit these 11.5" rotors with no spacers I'll probably go with them. I have konig flatouts in 15x8, so I don't think I can fit 11.75's at all, might be the same for 11.5" too.

Dynapros weigh about a pound more than dynalites, and they are slightly taller so you'll have harder time clearing things radially. I figure bigger rotors and lighter calipers is a fair trade!

aidandj

iTrader: (5)

Are you sure they are taller? Source?

hi_im_sean

iTrader: (3)

Just think, we track on stock calipers now. Anything should be a big improvement.

wilwood says a thing or 2 about the dimensions
http://www.wilwood.com/PDF/Flyers/fl104.pdf

ill let you find the pro

hi_im_sean

iTrader: (3)

OK I cant hold it anymore





































Theyre the same height.

But theyre wider by 0.080"....

aidandj

iTrader: (5)

Been there. It doesn't tell me as many dimensions as I wanted.

hi_im_sean

iTrader: (3)

What dimensions do you need that arnt there?

Subtract A from E gives you the height of the caliper from the lug centerline.They are both 2.06".

deezums

iTrader: (3)

I was wrong, they are the same. Page 2, follow disc diameter over to dimension E.
