Brake discs Zimmermann or GALFER

I've used Zimmerman rotors on a track day, they held up through a couple of sessions without warping. Seems decent enough for me.

I've run Zimmerman Z coat rotors on my GTI the whole time I've owned it and they're great.

Zimmerman is a reputable German part manufacturer, I run their rotors on my cars and never had an issue. They're also not that expensive all things considered.

I’d take Zimmerman everyday of the week and twice on Sunday.

Zimmerman is one of the best options for aftermarket rotors. I’ve ran them on all my cars.

I put a predator front engine mount and a Kinetic rear. The mechanics noticed that I had a warped brake disc, they changed the discs for Galfer and the brake pads. I had no more problems after that….

Zimmerman plain discs are great.

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 currently have Galfer, SRAM, and the Shimano Ice Tech rotors in 180/200-203.. Honestly…I’m hard pressed to tell the differences between them once I’m going downhill.

Zimmermann discs + Textar OEM pads

• After ~2 weeks → felt a clicking/grip when braking no squeak

• Recently brought it back again → they cleaned discs/pads applied lube and even replaced the pads

• Now 2 days later → clicking/grip is back + a new squeak at low speed in parking
