No. They won't easily swap. There are adapters out there but they aren't very cheap. Of course the other upgrades aren't exactly cheap either.
Our Hayabusa adapters aren't very expensive but you end up needing to get larger rotors as well as the calipers. BUT, the braking is incredible when done.
Now, I think I have a set of 4 piston adapters that I might give you for very cheap. These keep your stock rotors and use early 4 piston GSXR calipers. This does help a little bit but still not like the busa's
