Brake discs Centric or OEM BMW

I run centric blanks on a focus st and even on track the rotors haven’t been the problem and focuses are extremely hard on the front brakes because of the ediff. Pads and fluid is where you want to spend your money upgrades on brakes

I have heard from a few people now who do both autocross and lapping days to not get too fussed about rotor selection. Make sure your braking system is in good shape and replace parts as needed, but even the "cheap" rotors will do the job. I have a street/hybrid pad, relatively recent brake fluid, and Centric (I think) rotors off RockAuto. Been working well for me the past couple of years.

I have a non-pp GTI and threw on Centric blank rotors and powerstop z23 pads from Rockauto. Cost around $400 CAD including shipping and tax..super cheap.

No complaints about them, I would certainly buy them again. Very little brake dust but with a strong bite.

I got ASP pads & fully coated Centric rotors when I did my big brake swap & they treated me well.

I got 75k miles out of my plain centric rotors with hard track use on my GE

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

currently sitting at 179k km.

brake discs/pads/fluid

I switched to slotted, cyro treated centric rotors and they have been great. Went on in 2016 and have no complaints.

Otherwise Centric has been solid on most of my cars.

Centric makes ones that are painted black. I clean them up with brake cleaner and tape off the pad contact area, then use engine enamel spray paint to add an additional coat. I’m up in New England and one winter will do this to rotors. I do the same when I have to replace calipers. Lasts at least 3-4 years In my experience

the 325 rotors are tiny and have pitiful heat capacity
