are the part numbers for the hubs between years identical? the same caliper could be used if the dimensions on the hub itself were changed to accomodate the different rotors. i have GSX caliper but i have AEM rotors.. they never seated completely properly and slowly got worse vibration under hard braking over time. my car's a 1995 (8/94 build date) so i'm prolly the most fucked up as far as parts. my rear cylinders are completely different from the late 95-99... when looking for replacement rear cylinders i had to special order one listed under 1994 eclipse. go figure.

now that i think about it i wonder if this difference is related to my AEM rotor problems. if they made a universal rotor for all years when there should be different rotors for different years then we have a major problem. a $350 problem in my case. fuck. with the AEM's the caliper is offset with a bracket so that may have made it possible to use the wrong rotors.

hmmm but because the caliper 'floats' (it can move laterally) shouldn't it not matter if the rotor is centered in the bracket as long as it's not rubbing? the clamping of the caliper should automatically center the rotor in reference to the caliper (though not necessarily to the bracket).

i think this issue is important
