Default What backspacing should i run for skinnys up front?

Im looking to put billet specialties 15x4s and 15x10s on my 95 z28 and want to know what backspacing i should get for the front. Im pretty sure for the back people are say 7.5 but that could be wrong. let me know. Also, whats the most rubber i can get under the rear with a stock rear. I heard 275s but lemme know what you know

I found out from BS themselves to get the 15x4 with 1.62 bs you need to use a 5/16" spacer with them..

no spacer needed.. just grind the very edge of the caliper ever so slightly.. took me less than 1 min each side with the grinder...

15x4 with 1.625 backspacing

F-Body specific 15x10s with 7.5 backspacing


The amount of tire depends on who much you want to beat the inner fenders
