Brake discs Zimmermann or R1 Concepts

I used Zimmerman rotors

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

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

If you have no interest to do anything other than normal driving r1 concepts will work. If you so much as do a little "spirited driving" they will bake and turn into crappy brownies. And refuse any type of refund even with 500 miles on them. I honestly preferred OEM. They lasted a nice long time, minimal noise, and they were actually really nice on track

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.
