Brake discs Zimmermann or GiroDisc

The best combo was Zimmerman blanks and StopTech pads.

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.

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.

S2000 1 piece oem rotors last 2 weekends

Girodisc s2000 oem size 2 piece rotors lasted me almost 2 years of heavy tracking. They only died because my hawk er1 pads took a chunk out of one. They still had plenty of thickness

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.

Girodisc rotors are awesome and well proven across many vehicle brands.

Update for all those following along. My brakes were the best they've ever been today - on a very, very hot day (feels-like temp over 100). I had a vibration with light brake pressure, but pressed on giving more pressure and found that as the brakes got more heat in them, and I went deeper into the braking zone, the vibration disappeared. All was well, but after checking the rotors, they appear to have developed cracks.

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.
