Brakes/wheels C4/C3 combo question

My car is '87 Bird.



I already installed 15" C3 wheels like these:





Question is will i fit 12" C4 brakes or will there be any spindle/rotor/caliper issue?

Re: Brakes/wheels C4/C3 combo question

the C3 Vettes had 12" brakes on them with HUGE calipers... i'd say they would clear, but maybe find someone that has a C4 Vette with the brakes you are looking at getting and ask them if you can try your wheels on their car... but a better upgrade is the 98-02 F body "LS1" brakes, which are beefier than the C4 brakes, in which case you'd need to find someone with one of those cars to test fit your wheels..

Well havn't checked yet with C4 brakes, but LS1 brakes will fit, just LS1 calipers need 0,05" grind on ribs.

best regards
