Are all StopTech 355x32 Rotor Rings the same and would fit a Brembo GT kit?

[oceansize]

Something is wrong because my Stoptech rings have lasted 70 track days on the front and another 35 and counting on the rear. I use a fairly rotor unfriendly pad.

Could it be because of your car's weight, or should I say lack thereof?

Somewhat. This includes when the car was over 3000lbs. I have to check but I think I've been through 8 sets of pads on my oldest set of discs.

Maybe I got a bad batch or they changed something— this happened a decade ago at this point.

I am curious to know which pads to get for the same type of driving conditions. I like a good initial bite on braking and obviously something that doesn't fade, cause a lot noise or dust.

I may be asking for the impossible, hahaha.

Endless MX87. I have a set on my daily driver and they've been fantastic. We can usually special order them in if they're not available in your shapes, this typically takes 8 weeks.

That's very unusual. What pads?

PF01, Stoptech SR34 and Hawk DTC70. I think I had one set of Pagid Yellows at one point.

I don’t think it’s unusual. I know of 4 others with a Stoptech BBK that also get pretty long life from the 355 Stoptechs

The 380mm Stoptech BBK on my E90 M3 has over 80k miles on the rotors. Probably been through over 10 sets of pads on the fronts.

I’ve seen too many instances of these rotors performing and lasting a long time to believe that the Stoptech rings are crap. Hard to get nowadays? Yes.

Can anyone confirm that they have fitted

31.737.1102.87
and
31.737.1101.87

or


31.737.1102.99
and
31.737.1101.99

to their front Brembo hats without any issues?


Also what about the rear rotor 345x28 Stoptech rotor rings? Anyone fit them to Brembo hats without issues? Zeckhausen's site is stating that the Stoptech rotor rings require the Brembo rear hats to be machined in order for them to fit.
