Brake discs R1 Concepts or OEM BMW

I’ve been running these for a few years….much better than the stock oem

These guys make great stuff and their customer service, if you need it, is exceptional. Only thing I put on my cars. My Mazda CX5 has drilled and slotted rotors, and my 13 C70 has slotted rotors. I will probably go with the Geo Carbons when my S60 needs them as I talked to a V60 owner that had them and he said those were the ones to get.

Absolutely normal. But I would still get one which is coated. My R1 Concepts from Rock Auto were completely black with a Zinc coating

i bought used 2011 528i RWD N52 engine with 120k km 5 years ago.

currently sitting at 179k km.

brake discs/pads/fluid

I’ve got the R1 concept drilled/slotted rotors and ceramic pads, felt a decent difference from the OEM but my rotors and pads were at about 35% life so it makes sense that I’d feel a good difference. I do some spirited driving around town and the brakes perform pretty great.

Bought my 2018 Stinger GT new - within a few months my steering would shake like it had warped rotors - and it wasnt always the case - it would be ok at times, then come back. I use Auto Hold a lot - and it seems that feature causes the shaking in the steering wheel the more I used it. I did talk with Kia about it and they dismissed it and said it was fine - after being sick and tired of the shaking I went and bought new rotors and pads from R1 Concepts and havent looked back - no issues at all since I installed them and I use Auto Hold every single day.

Saves energy when braking. Its really satisfying to see the range go up when slowly braking downhill. This also saves your brake discs from wearing out fast, (just remember to use the brakes some times so they dont rust).

R1 concept is what I use, with the drilled and slowed with there performance pads, works very good and at a low cost , plus the rotors look awesome on the car.

Ever notice how BMW does not use cross drilled rotors. I think Porshe is also open about the fact they only use them for the looks. HMMMM

BMW OEM rotors after 4 years and 35k miles. Junk build quality now
