Ok, this is pretty messed up...I got the dual piston GSX front calipers, and rotors for a 98 GSX. Got it all bolted up, and the rotors were not the right size..they were *around* 1/16" wider, and the same smaller in diameter..(the rotor actually just barely touches the caliper bracket and pad shims) Checked the rotor part#'s with almost every manufacturer out there, including the dealer..Found out that from 95-97, is one rotor part#, and 98-99 is the other rotor part#, both for GSX AWD fronts..The strange thing is, all the part#'s for loaded calipers are IDENTICAL for 95-99..I just don't get it..So I ended up just getting the rotors for 95-97, and fit just perfectly..Anyone know the difference from 97 to 98+?? The ONLY thing i can think of is that the caliper brackets are diff on the 98+, but that still doesnt explain why all the loaded caliper#'s are the same throughout the years...Am I missing something here? haha..BTW, these brakes are sweet :)
