Anyone tested RB Performance Rotors?

Came across these and they are a OEM option for Rotors. Has anyone tested/run these discs? Any installation, operating issues with OEM brakes?

BimmerRob08,

I have used them on 335i with great results. They hold up much better than both stock & DBA 5000 series (slotted) rotors.
As for the heavier BMW E9X M3, I have just put an order for a set of front and rear RacingBrakes (Open-Slot) rotors. I will be able to give my review once i receive, install and test them.

They make GREAT stuff. Track junkies use them all the time on BimmerForums.
I was in contact with them years ago about making a BBK for our car. I guess they got as far as the rotors.

Cool, please let us know for sure. I'd also be curious how much weight savings over the OEM rotors if any.

My M3 doesn't need anything more than the stock setup as it's only street driven, but I definitely wouldn't mind some performance increase. Problem is these are almost twice as expensive as the OEM rotors.

Thanks for the inputs fella's. I'm on the fence about going with these rotors so glad to hear positive inputs from users.

Cheers,
RB

Keep in mind, these maybe more money up front, but they may last a lot longer than OE rotors, which are designed to be replaced with the pads. And when it's time to replace them, you only replace the rings and maybe the mounting hardware.

Found the replacement rotor kit that includes the hardware.

I loved mine and I never had any problems with their rotors and/or 4pot caliper kit.

As long as you are using them for street, autocross and very light track day you are okay.

We don't recommend them for medium to heavy track use and with track pads due to the possibility of rotor cracking.

I am bumping this old thread, because i want some feedback from e9x m3 owners that have used them on the track.
These rotors are slotted and save 4.7 pounds per each front rotor which is a big deal.
I have used RB rotors on my 135i for 2 seasons and they are great. But that car is about 300 pounds lighter.
There were some negative reviews in the past, and Harold in the post above does not recommend them for track use
Would be interested to hear m3 owners opinion

I've put about 3k miles on mine and never had any problems, so I'd give them another go if I had another car.
