they should but i am not positive. i am currently in the process of changing a 93 gsx750f into a gsxr1000r so far the engin bolts up good and the fairings are mountable.
Contrary to what the speedometer might say (and GSXR 750 owners), a 2008 GSXR does not have the displacement to reach 180mph. A road test conducted in Germany had a rider reach 181mph - or what said...
