Hey guys, I recently drove a friends Audi S4 and thought the brakes were amazing. I'm not sure on the specs of the system or the number of pistons in each caliper, but they were blank (non-slotted, non-crossdrilled) discs. Does anyone know where I could get similar high-end blanks? Are the OEM or Brembo blanks my only choice? Does anyone know of blanks that are painted like the rotora or racingbrake rotors? Thanks in advance.
