Hi all, been trying to find out what are the best front disc/calliper upgrade would be for my VR6 Caddy without converting to 5 stud and spending an obscene amount. At present I have standard sdi brakes (I know the front of a caddy is basically a polo), can I get 312mm discs/brakes with 4 stud or should I just settle for VR6 setup? Thanks in advance, Lee
