That's a better price than I found. I paid $579+ shipping from HPA. Where did you buy them? Provided you don't mind sharing.
TIA

My M2 got its first trackday today. I had RS29 at the front and OEM at the rear. And Motul 600. Other than that all stock incl the Michelin PSSs. Drove 180 km on track and everything worked flawlessly

I bought some Carbotech xp10s for the front and xp8s for the rear. Will see how they work out next weekend at Road America.

Are the BMW M brakes from Brembo?

Yes.

They are Brembo, but not the same Brembo you see on big brake kits. Most OEM style Brembo calipers can't perform at the same level as the aftermarket version.

I have m4 sport pads front and mp rear pads on m135i with mpbbk. I believe m4 sport pads are oem branded rs29. Same findings as yours ie all works well on road and track.

Why are the pad "clanking"? Shouldn't they fit like the stock pads?

[omasou]

Since the calipers unlike the ATE style are closed...What is the recommended method for retracting the pistons to remove the pads and then further retracting them to put in the new thicker pads.

The videos I have seen so far assume you're changing pads and leverage against the old pad.

[caminator]

anyone got a good link to someone selling RS29s in Europe?

When I saw a set of Mperformance brakepads for the M4, there was TEXTAR printed on the back....yes I know the standard brakepads are also from TEXTAR.

Are they close (with upgraded brakepads, brake oil) or still a massive difference?

Found this on another forum

BMW sold sport pads at least for the E9x in Europe. These were Textar and came in BMW box and black in color. Pagid is a subdivision of Textar (their motorsport arm). Spoke to BlackFalcon Racing team and was told basically you are buying Pagid pads through the dealership (the sport pad and likely this M Sport you are referring to is Pagid). Go with whats cheaper, in the E9X case, it was Pagid being cheaper. Wouldnt be surprised if this is the case here too.

Brembo or any other aftermarket front calipers are 6 pistons vs the OE 4 pistons. Brembo GT Monoblock caliper is also stiffer and have minimum deflection under heavy usage.

The rotor used is also a true two piece that is not only larger in diameter, but thicker and with improved vane design.

For light to medium duty usage the OEM Brembo with upgraded pads(RS29), high temp fluid and SS lines should be fine. Some track guys will upgrade to the Stoptech or other true two-piece rotors for improved cooling and to remove a few pounds of unsprung weight from each corner. If you are consistently overheating your brakes with the above uprades and it's not a brake management issue then it's time to upgrade to an aftermarket brake system.

Indeed I know how good the aftermarket BBK can be... I have a full AP racing BBK (6 pot front, 4 pot rear) with Pagid pads on my Z4M. I installed them for trackdays. When comparing the AP brakes and the crappy Z4M brakes....the difference is night and day. The OEM steel brakes of the F M4, M3, M2 are the best ones fitted on a M-car till today (when you compare it with previous brakes on older normal M-cars)... The OEM M brakes are better then before and I was wondering if the difference is still that big with an aftermarket BBK.

You are right, the current F8x M brakes are the best to date. The OEM Brembo definitely bridge that gap a lot, but still left something on the table.

After using stoptech on my last car, I would not use them again. My goal is to leave the M2 with stock calipers and rotors. If that doesn't happen I would use AP racing or Brembo. Stoptech was low quality and had lacking support. They stopped well but seals would leak super early require rebuilds which they wouldn't warranty. There is a reason AP Racing and Brembo are so more much money.

That is not very typical of Stoptech and we have dealt with them for the past 11+ years. You may have had a bad caliper or two? Was it a Trophy Sport/Race or a standard caliper? What did you use them for?

In our Time Attack days the brakes held for 2 entire seasons, then it was sold used and stayed on a customer's track only car for a couple of more years.

AP by Essex should be on the top of your list as Brembo GT will likely suffer the same fate if used under the same conditions as the Stoptech.

These went on a customer's M2 along with MCS 2-way NR.

Hey guys

I've got a set of RS29s for a trackday on Sunday.

Those of you who've used them, did you follow a bedding in procedure before getting on track?

I used them in an admittedly very hard application, stopping a 420 wheel horsepower X1 35i that weighed almost 4k lbs with a driver in it. They would only last 10 track days before they would leak on the bleed screw. While it was a difficult application (rotors were only 355mm, which was really way too small but that's the biggest they made for the 335i), this is common problem with stoptech if you google it. https://www.google.com/webhp?sourcei...eaking%20fluid

Ap Racing brakes and MCS 2 way would be an unbelievably good setup for the M2, and if I can convince myself to drop the money that is my goal eventually.

Yes. First mechanical bedding and then heat.

[AutoTalent]

I can get these pads for anyone interested!
