Brake discs R1 Concepts or OEM BMW

I’ve been buying rotors for over 15 years from R1 Concepts and highly recommend them. Good quality and good price.

I got the the black R1 Concepts slotted and drilled ones for mine, thinking the same thing about the cosmetics. But the black wore off after a few stops. Still good breaks tho.

I have r1 concepts on right now. They haven't treated me bad at all.

I just bought a set of all 4 cross drilled slotted rotors with the black anti rust coating all around with a set of ceramic brake pads front and back and hardware. Brand name R1 concepts.

I got R1 concepts drilled and slotted rotors and ceramic pads and they've been awesome.

I just put a set of R1 Concepts drilled and slotted rotors with ceramic pads. Huge improvement over OEM.

Great quality at a decent price. I've been using them for almost 15 years on everythinng from a minivan to 2 BMWs.

R1 concepts drilled and slotted. Been running them for about two years and theyre solid.

I've purchased my brakes and rotors from R1 Concepts. They're not that bad. I went with oem style rotors and ceramic brake pads.

the 325 rotors are tiny and have pitiful heat capacity
