Ive got Ksport 6 pots 286mm? I've got fortran ssv wheels (JDM) and there is 1mm max gap between caliper, and wheels., people say they're an overkill, but I think they are one of the best things I've bought. 130mph into a corner at Donnington wasn't fun when I had NO brakes (cooked/cracked standard), now with the 6 pots they dont have any change in feel, or cook after a full track day! If you're going to track it, spend the money on decent stuff, if its a fast road car/street, standard are ususally ok if all working right, decent discs and decent pads.
