looking for high performance rotors from Galfer, braking, braketech, Brembo, Berlinger etc. ideally for 2011+ GSXR 600/7500. The size is 310mm Burton I might be able to do 320mm if you have the spacers. I only ask that you ping me via PM. W/pics of the units and to ensure they are in spec an you shoot me current thickness on them. Thanks IJB
