Ive just had to fit new Ap disc's and pads to the race car. The disc's are on floating bells and the pads that were fitted before were Pagid Blacks RS-14 ceramic's. I have found these to be awsome I can out brake anything in my series apart from the touring cars. So im intending to use them again. I just wondered if anyone has had any experience in using them in a 4/6 pot application before. Cheers Mike
