Front brake disc thickness
I've recently bought a late Tomcat VVC and am looking to revamp the brakes. I always thought the later 'bubble dash' cars had a lot in common with the R3 200
and that the front vented brakes on the R8 200/400 cars were the same as the later R3 200 and HHR 400 cars. However it seems the vented discs on these later cars are 21mm thick whereas the equivalent R8 discs are thicker at 22mm. For some reason the thicker (by 1mm!) discs are coming out at nearly twice the price so has anyone used the 21mm discs on their R8 without detriment to the braking performance or am I asking for trouble?
