Brake discs Zimmermann or OEM Volkswagen

According to the newsletter today, Rock Auto has added Zimmerman to their catalog. They have some for Phaetons if yours has the smaller front rotors.

I used Zimmermann replacements discs and pads on my B9 RS4 for 5 years/70k miles. Had 3 sets all around over that time. The front discs and calipers are the same as the etron. They were good products and hard to tell the difference from OEM.

I replaced the front pads and rotors on my F20 M135i yesterday. Same Brembo brakes as yours. I did a lot of research, and there isn't really "better" than stock for the same money. The only better option would be to upgrade to bigger brakes, but that would cost way more. I ended up going with Zimmerman Z-coat two piece rotors and ATE pads. The Zimmerman rotors are the slotted and dimpled versions. BMW calls that the M Performance rotors as OE. They're the same size - 340mm. They reportedly don't give much of a performance increase, but they weigh about 8% less than standard discs. All together with the hardware (guide pins, caliper bolts, etc) was about £500 with shipping from Spareto.

ngl i just installed zimmerman rotors and they probably had that too but no problems

I ordered zimmerman rotors and genaric TWR ceramic pads

I just did pads and rotors on my '19 Alltrack. I went with Bosch Quietcast pads and Zimmermann rotors from FCP Euro. So much better than the OEM I removed.

Zimmermann Rotors / IS2000 Pads

One of my front rotors on my 2019 was showing significant grooving by about 1500 miles. At 12k miles, it isn't really all that much worse. No pulsing or judder.

Ordered zimmerman f brake discs and they were not riveted tight enough. The two-piece brake disc made a clicking noise when braking at low speed.

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