Hi Guys.I have a set of 2007 Gsxr1000 wheels,I installed the rear with no problem but had to install a Busa gen1 brake disk I know is a little smaller.But here is the tricky part i try to install the front one and wont fin as easy as the rear,I made spacers for the disk and shaft because the busa wheel is wider but still have problem.Anyone did that mod and have the measures for the spacers needed. lease:
