Rear will bolt up but the brake and rotor are bigger and the caliper hanger needs a place to slide in,but that can be worked.. front rotors are way off..you could swap out newer gixxer or busa forks to make them work..
If You want lighter rims you Better off trying to make 05-08 gsxr rims work..never did it but seen it done on the boards,think just a spacer?..
