Brake discs R1 Concepts or OEM BMW

R1 Concepts are the only brakes I use on my cars. Last far longer then OEM.

I just ordered pads, rotors and sensors for my 16 M235i. Cost out the door was $1000 for BMW OEM parts. Rotors are each unless it's bought in a kit. ($177 each) Rotors are likely smaller on the rear wheels.

Have been putting r1concept rotors on my vehicles for 10 years. Corolla, lexus is 250, ford f150, saab 9-3, volvo xc 90. Have always gotten drilled/slotted braking performance seems to be twice as good. The last few cars I know I got my geomet rotors and ceramic pads. But 8 years ago got rotors on my lexus. Felt great never really had a problem. I was showing off in the back roads of wv, super hill, county roads. Maybe a 20 minute drive and I did have the car filled with people. Hit 95 mph a couple times. Everything was fine got back parked, my back rotors were smoking for atleast 10 minutes very visible. Still never had any issues after that. That is apparently super common. Not cause for too much concern. Never had it with any other vehicle any other time. I speed excisively. Just saying if you intend to use them for a track car I'd wanna be aware of that. Who knows if the geomet rotors would've improved things.

I have a drilled and slotted set with performance pads from R1 Concepts (was going ti replace pads but 1 rotor was bad). I have had them for about 4 months now and only complaint us the squeeky pads. I have a larger vehicle (Forester) so i feel the fade a bit sooner than most, but i feel these rotors do a good job of preventing that. I dont ride the brakea that hard but its still noticable.

I've installed drilled and slotted rotors on my pickup, BMW X5, and just ordered a set for my BMW Z3. I live in the mountains, drive spirited, and definitely have improved braking performance with them. Make sure you bed the pads in correctly.

I have been using r1concepts brakes since my first car over a decade ago. There brakes can be found at jegs, amazon and rock auto. Compared a 2021 receipt to current. I don't have any experience with powerstop. But r1 concepts brakes are way better then factory I've gotten metallic and ceramic pads the eline and geo line of rotors. Geo was so good. Typical rotors in the winter when you park in the garage and the next day the first brake has that squeal where your breaking the rust off of the rotor the geos never had that problem. I always got drilled and slotted and it definitely significantly improved breaking and I never had an R1concept rotor fail.

I’ve been getting r1 concepts after the oem rotors warped, never had a problem since.

I bought R1 Concepts vented and slotted rotors and EBC Yellow stuff brake pads. This is on my 2021 AWD Turbo. I still got more break in to do, but the difference is huge and immediately noticeable.

have drilled and slotted rotors for it with pads not installed, only problems are it needs the new brakes installed the current ones are warped

the 325 rotors are tiny and have pitiful heat capacity
