I'll trade you my 06 gsxr calipers for your r6 calipers
Yes they swap I'll be putting a set on my gixxer. The r6 calipers need a washer under them if they are going on the gsxr or they'll rub on the rotors. Apparently they are a brembo design and have way better feel and less brake fade.
Guys, brakes only slow you down!
oh and yes, 04-06 r1 and the 06+ r6 calipers are the same and are monoblock colin.
