Will 03-06 rear caliper bolt up?

There differnt the 03-06 are hydro brakes.... the older ones are cable...

Awk makes a conversion look in his sig piece is says awks gsxr brakes it will work to make urs hydro....

Alot of people on the forum run them there good brakes from what i hear...
no personal experice though because i have an 03 already got the hydro brakes
 
The 03+ hydro
Calipers do not directly bolt to the pre 03 carriers,
I believe you'll need the whole rearend, carrier, axle, brake hub/disc and all
 
If i remember right on the older style the disk moves and the caliper is stationary, And the newer models are the opposite.
