Brake discs ATE or Zimmermann

I used Zimmerman rotors

The ATE disks are made from the same cores it seems, but they are coated entirely in some matte grey coating, the BMW ones aren’t, that’s the difference that I have noted.

I have been driving multiple BMWs for almost 20 years and have always used Zimmermans as replacement rotors. I will keep buying them.

The online vendors offer Zimmerman/Akebono kits, I installed one on the front of my E92 and brake dust is nearly eliminated. The Akebono Ceramic pads might have slightly less bite but I'm happy with them.

OE is likely ATE or Pagid. Zimmermann is totally 100% fine OEM alternative.

Zimmermann's Coat Z rotors are excellent. I've used them on many BMWs with no issues.

I personally have the Zimmerman Rotors, and Akebono pads. Great, cheap setup.

Zimmerman-Akebono combination is blizz

Zimmerman rotors (heavier then I would like)

I’m getting issues with rotors warping on my 2002 E53. I bought Zimmermann smooth rotors couple of years ago and they’ve been lathed couple of times now. At one point I had to replace Zimmermann pads too as they were excreting glue or something that caused “falling stars” on the rotor faces.
