Brake discs Zimmermann or OEM Volkswagen

I used both before Zimmerman is good and cheap. Akebento are good too but hard to find and more expense. I practically used all brake pads and rotors over the 13 years I own the RRS. I would recommend using cermpads.

Zimmerman rotors and Hawk HPS pads. Rotors are not drilled or slotted. The car stops on a dime and just saved me on the highway yesterday. This was the first modification I did and I'm glad I did it.

Zimmerman makes great rotors.

Had the same dilemma a few weeks back. Went with Zimmermann drilled rotors paired with EBC red. So far I've been pleased with them.

Brakes are doing great.

I just recently did the back brakes at 37k and the fronts last weekend at 39k on my 2020 M340i. Dealer said rotors were at min thickness last June but I waited for the sensors to actually trip and even then I got 1k+ miles with a good bit of pad life left still. Went with Zimmerman rotors and OEM pads from FCP Euro and second that combo. I read too many hit or miss stories about non-OEM pads, I don’t track my car, and brake dust aside like OEM brake feel.

Yes. Replace the rotors with each service. I run Zimmerman rotors and either BMW or TRW pads.

I'm using Zimmerman rotors and Textar pads. 11k miles and no complaints so far.

Do both. The stock rotors are pretty garbage and cover your car in iron anyways.

my brakes started to vibrate a bit when braking at or above 70mph, and it's only progressively gotten worse. From the first inspection (always at the same dealer I bought it from), I've asked the techs to double check the rotors, as it just didn't seem right to me, but they always brushed it off as normal and no big deal. I just took it in for an inspection (now at 22,700~ miles), and they tell me that yes, my rotors are warped, and that I'll need to replace the rotors and pads to alleviate the issue.
