Hello all- BIRA.org lists a UFO conversion using Porsche 996 calipers and "Mercedes V12" Rotors (320x30). Has anyone done this? I'm hoping to find out what year and model V12 disk I need. I assume it's the 600, but the early years took a different offset rotor. Big Aloha, Adam- 200 20v Avant -Jungle Racer
