Brake discs Zimmermann or R1 Concepts

finally got r1 concepts put on about 5 days ago. drilled and slotted rotors. SMOOTH like butter

Ive got r1s on 3 of my cars and love them. Put out a decent amount of brake dust so either learn to live with it or youll be finger banging your wheels to keep them clean. Working on set #2 on my camry, lasted about 40k miles but i drive hard. Handled well thru the mountains

Zimmerman plain discs are great.

I went with R1 Concepts for the front..thats with slotted and drilled rotors and pads and im happy with them. I've run them about 6k miles so far and no issues.

I was more than happy with my R1 Rotors at Sonoma 2 weeks ago. I felt a bit of pulsing when I got the brakes especially hot, but I never had any real fading.

Got Zimmerman’s on my 328 sport. I think I’m going on 50,000 miles on them and they’re still performing well and aren’t rusty. Zimmerman‘s rep is as one of the best aftermarket rotors

I have Zimmerman rotors and akebono ceramic pads on a 2018 base. They are great. 90% less dust on rims.

I always use Zimmerman coated rotors and Hawk HPS pads on my street Audis. Pads tend to last about 100,000 miles.

I've had them on my wife's car for 2 years. Haven't had any problems other than the rust

I purchased a 99 M3 recently and the car came with Zimmerman “Sport” drilled rotors and Jurid brake pads and I have to say that they are a terrible combo. They squeak a lot and they maybe have less than 10k miles on them.
