I'm pretty sure there are several threads on this.


I have Stoptechs myself....
Are you looking for something in particular?

AP Racing and Rotora come to mind as well.

There's also K-Sport but that stuff is garbage.

Should be possible, but might require a custom bracket to be fabricated.

Good to note that Brembo owns AP Racing now.

Have you driven beyond the ability of OEMs? The stock brakes work very well and can hold up to quite a bit. I've tracked my Moupe many times and just gone with track pads (PFC 01s), SS lines and high temp fluid changes without any fade at all after a full day or weekend on the track. I can think of other areas of the car that I would spend BBK money on before upgrading the brakes. Just my .02 worth.

Thanks for your suggestion, it is good idea to save money on other parts first. but I would like to know option for the brake kit.

Randy's point on saving money was only half the takeaway, the other half being do you actually feel the need to purchase a bbk given that 1) on the street it won't yield any better braking over stock and 2) on the track if you are experiencing fade with the stock setup, you could easily upgrade pads and fluid only for a fraction of the cost and achieve the same results as a bbk.

If you're doing this for looks then both points above are moot. To answer your question, the following companies offer a bbk: Stoptech, Brembo, AP, Alcon, Wildwood, K-sport and Rotora. If it were my money I'd go with either of the first 3, although Stoptech appears to be the cheapest of the 3.

I have Stoptech 355mm, 6 piston front, 4 piston rear, with stock wheels, you need at least 12mm spacers for the front wheels to fit.

I haven't actually done a test fit on the stock wheel.
If you need the info, I have a stock wheel sitting here and can get some clearance data for you.
Let me know.

Like GA41 wrote, you need at least 12mm spacers for the fronts with stock rims. I have Stoptech and have run it with stock rims. The rears are fine without it but look nice pushed out with the 12mm spacer.

Did the same as well. I have both front and rear but mine are 12.5mm Turner Motorsport spacers.

The RacingBrake kit requires a 5mm spacer to clear the front. If you run the rears up front then no spacers.

Thanks for your offer, but I've bought a Brembo monobloc 6 kit and I think that they're more big than ST6: it's only to know if I must buy also the spacers BEFORE to install it ......
Really, I don't understand WHY on Brembo website absolutely nothing for problem to use it: if I need to change suspension, wheels or must use spacers, EVERY caliper fit !!

.....I've a extra set of 224M, but, with stock suspension, 9ET30 fit ??
I don't think: I read that some problem to fit the 359M, and they're 9ET31....
And also with 225/45 it's very stretched ....
