Hi everyone, buying myself some 6 pots this week need to know some info i have a 2008 8p s3 with standard 18" wheels. I read that Porsche cayenne z18 brake calipers bolt right on. And I can then run GL450 discs (350mm). Can anyone confirm this, do I need adapters and spacers? Looking for the simplest answer so I know what I need to buy in order to make these fit. Cheers.
