I have a Mini S rotor, but I thought we decided they might be a little too thick to fit under the caliper right?

I think if they fit the 8s, they will fit the 9s. The "lip" on 9s should be closer to the hub than the 8s assuming the same wheel. Im sure threre are differnces bewteen brands and models though. The real trick will be if they fit my 15x6.5 konig lace street wheels. Thats why im kind of glad we are limited to an 11" rotor with the way we are looking at doing this. That extra 3/8" on the radius with the 11.75" rotors could make all the difference with my street wheels.

But yea, we can definitely ship brackets around and play some wheel fitment shell games. Or just send me a decent drawing, and I can fab some up to test.

<p>I thought we were doing the JCW rotor, more like 11.75&quot;</p>

Regular mini is 11", Mini S is 11.5. I think JCW's uses 12.5" rotors, right?

Mini is 280mm, Mini S 294mm, JCW 316mm, all 22mm wide

Mini S rears are 259x10mm solids

yup

nominal thickness of cooper rotor is 0.866"

miata caliper nominal max is 0.787"

willwood caliper(all the ones weve been looking at) nominal max is 0.810"


Willwood does make calipers that accept 1" rotors. Need to make sure those take a standard pad.


And yea, last I remember we were discussing a few 11" options or the 11.5" cooper S

Just as a point of clarification, I'm using a

Rotor: Centric 121.34100



Caliper: Wilwood Dynalite 120-6806



Pads: Wilwood 7112


(Granted, I'm using Carbotech pads, but the dimensions should be standard.)

I'm confused because this thread is all over the place... are you guys just repeating the work that relte already did?

<p>I see 294mm for the JWC rotor. 11.5&quot;</p><p>With big brakes like these I don't see us needing to replace rotors very often. Also, G has a kit that used the mini rotors.</p>

<p>I thought we were going to try and use the 11.5&quot; rotors.</p>

Ok, just checking. I wanted to make sure I was supplying valid information because I'm seeing things aaaallllll over the place up in herr

aidandj

iTrader: (5)

<p>That information is good. It means that the mini rotors do fit under the wilwood calipers.</p>

hi_im_sean

iTrader: (3)

yea, 11.5, or just copy previous work. And if im not mistaken bobbundy did that before relte

Oh snap, totally missed that connection. Awesome!

So 11.5" S rotors and dynalites or pros it is?

Looks like there are 5 options for caliper thickness, from 9.7-31.8mm

The 1"/22.5mm caliper would clear no sweat, 1/2" for the rear...

<p>Yes, that is the plan. I'm going to spend lunch calling some second hand circle track shops and trying to get my hands on some used calipers.</p><p>What is the actual difference between different &quot;thickness&quot; calipers.</p>

aidandj

iTrader: (5)

<p>Lol. Eo2k just posted that link.</p><p>Are the S rotors 11.5? Or the JWC rotors? Or are they the same?</p>

One thing ive keep quiet because I dont want endless Pms from you ******* trying to save $5 on a set of calipers(s10 forum lesson learned):

My good friend and riding buddy is a wilwood dealer. Wilwood works with volume. If I buy 1 dynalite from him, his cost is more than summitracing sells them for. But, if we buy qty. then price goes down accordingly. Not sure how much saving, but its worth a try.

Dynalites are three piece, I bet the third piece is different thickness to get different thickness calipers.

Mini Cooper S rotors are 11.5, not JCW. JCW is 12.5"

I am nearly 99.9% positive about the above

hi_im_sean

It just determines the thickest rotor it can slide over with new pads installed. There is only so much room between the casting and the piston when its fully retracted.

Im seeing 12" for the JCWs?

We want to R&D these on used caliper, or maybe one of us buys one to test fitments. When we open up the group buy and want to order 100+ calipers is when we are going to want to talk to my buddy.

Not too worried about this forum, much more mature than a mini truck forum.
