Brake discs Zimmermann or Centric

I buy Centric from Rock Auto. Then I have my local shop install them. Labor is $165 for an "axle" (so $330 front and back) and rotors/pads cost me about $125 a pair or $250 for all four.

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.

I did centric rotors and akebono pads up front. Works fine.

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.

Be aware, the dimples and slots make for more noise so don’t expect them to be identical to the blank rotors in that regard.

Tbh drilled Zimmermann Discs are imho Junk. They use OEM Discs. Had so many Problems with Vibrations, warped Discs and so on.
