Premium Brakes? I have them, and have to say they're a necessity. However, I find that over 160km/h under hard braking the vibration is horrendous. I would suspect the grooves on the rotors although I am unsure.
The standard brakes are WOFTAM on the XR8. If I had my time again I'd still go the Premiums. Only other drawbacks are the brake dust, and the fact that I seriously suspect the rotors will be worn to limits after just one set of pads!
