Brake discs Zimmermann or GALFER

I got Zimmerman blanks and Ferodo Racing DS2500 pads and love that combo for track/street. They can be a bit noisy when cold and light braking on the street but if you just brake a bit harder no noise at all.

I went with Zimmerman blanks and Hawk HPS pads (non 5.0), been very happy with them.

Heard good things about galfer rotors

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.

My local shop recommended trying Galfer rotors which is what they run with Maguras and it’s made a difference on my front brake which is the only one I have had rub issues with. Galfer rotor with new pads took about a week to break in with no rub.

I’m running Galfer Wave rotors 203/180 with the E-bike pads front, pro pads rear. It’s so much more brake than I will ever need.

I have Code RSC's on my current bike and got rid of the SRAM rotors and now run Galfer wave rotors along with MTX gold pads.

I have etc red and they work, but I used Zimmerman rotors and never again. Don't go cheap

I’m getting issues with rotors warping on my 2002 E53. I bought Zimmermann smooth rotors couple of years ago and they’ve been lathed couple of times now. At one point I had to replace Zimmermann pads too as they were excreting glue or something that caused “falling stars” on the rotor faces.
