Brake discs Zimmermann or Bosch

I went with Zimmerman rotors and oem pads on my M340i. Perfectly happy with the cost savings over the oem rotors.

You mention cost but not weight differential of the rotors, many people move to girodisks because it reduces the weight at each corner. With regards to blanks vs drilled, I have had no issues running drilled (Zimmerman) on my previous Audi TTs and my current 718. I run a dedicated set for track with Carbotech XP12s, no fade, no issues. 718 is in roughly the same weight category, 3k ish.

I had my V60t6 2020 done for 800$ with Zimmerman rotors and Hawk pads (high performance). The job was done by 2 technicians within 1h.

Solid, Zinc coated Zimmermann with Red Stuff pads. I'm stage 1 and push my car a bit occasionally and have never had any issues stopping when I want to.

I replaced my previous rotors with Zimmerman ones and they also had this notch so don’t worry about it as it’s normal.

My CRV and Odyssey are on Bosch rotors and pads from rockauto. They’re great thus far. Only complaint is that I ended up using pad clips from Honda because the Bosch ones didn’t fit as good on the CRV but were excellent on the Oddy.

I used Zimmerman rotors and ATE ceramic pads all purchased from fcpeuro.com. With stock pads I could wash the car and within two days they would be brown from brake dust. Now I can go weeks before I start to notice that there may be a little dust.

With the ceramic pads I cannot tell a difference in braking, I have almost no brake dust, and the rotors still look like new.

I just bought Bosch rotors and akebono pads on Amazon with a bottle of brake fluid. Works fine.

I did Zimmerman/Akebono on my e39 about 3000 mikes ago. My only complaint is the bite. It doesn't have that initial braking force the OEM pads had. It still slows the car down without fail, just a different feel.

I do not recommend Zimmermann, while they work ok for a lot of people, i had a lot of problems with the rotors.
