Just in case anybody wanted to know the Busa front rotors are a direct swap with the 2006 GSXR600. Hub center diameter is 120mm and the bolt holes all match up too. So if you want to upgrade your front brake rotors get these and they fit. I just got in a new set of Galfer waves and they look great !! I cant wait to try them along with the pads and lines too.
