Brake discs Zimmermann or POWER STOP

I got Zimmermann coated rotors and TRW Ultra ceramic pads, but I just daily mine and it never sees the track.

Zimmerman blanks and EBC reds have been great for me

I would run Zimmerman Sport drilled rotors on my A4 with EBC yellows and they were outstanding.

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 ran their track pads and rotors on my WRX before I put Brembos on it and had good performance. They’ll likely be fine unless you’re a super serious track driver (but if you were you probably wouldn’t be asking this question).

I run those rotors with their track day pads on track and have loved their performance.

I have the zimmermans, and I've heard numerous people tell me they've seen and heard of them cracking under heavy heated use. It kinda worries me a little, but they've been solid so far, and I've yet to really roast them... Honnestly if I were to do it again, I would probably go with the brembos even though they may be a little more expensive. whats more important to stopping, is pads. The difference between the stopping power and feel of different pads varries greatly. I've had some heavy carbon kevlar pads that took a long while to warm up but once they were warm grabbed really well, but they were kinda hard for regular street driving. I've used stock pads which pretty much suck but last forever, and I've used some softer sport street pads that wear and dust a little more, but stop far supperior to oters for regular street driving. I've yet to push them to the point of fade, but we'll see where that goes once I've got the suspension and bleeding sorted

I replaced mine with Power Stop rotors and pads at about 60k and noticed zero difference in braking after. They also only lasted 20k miles before the rotors started to warp. Just put OEMs back on. Absolutely not worth it.
