Z32 brake swap help!!

[dynastyjam]

hey guys ,

ok, maybe im just being reallly stupid and missing something here, but for some reason, the front swap aint working...

i bought 30mm aluminum calipers from a 91, and 28mm brembo rotors. but rather than the rotors being too small for the calipers, its actually the other way around, which makes no sense to me.

now i know everyones probably thinking the sizes are just wrong, ...but theyre not, so i dont get it. anyone have a solution? are the pistons sticking out too far maybe? though it dont look like it

i will post pics if you guys nee to see, or dont understand what im saying

It is possible that something may have been mis-packaged. I do see it from time to time... but a pic would also help please.
