Default 1 7/8th backspacing holeshots

for the 15x4 hole shot holestars for the fronts is this the correct backspacing?

will I have to run a spacer?

the backs are 15x10 7 7/8th spacing.

I believe you will need a .075 spacer to clear the brakes. Measure the distance from the outside of the disk hub (where the wheel stud comes through the disk rotor) to the outer portion of the brake caliper, then add .025 for clearance and then add that total to your 1 7/8th measurement . I used a straight edge on the caliper and measured off the wheel stud.

My 95 Z28 required 2 7/8ths offset with a 3/4" spacer to tuck nicely under the fender.

I run the same back wheel size and offset and it fits fine with no spacer. I am running a 98 rear brake setup with drum type emergency brake.

Hope this helps

how much do you have to grind on the front?

the other guys 93sec and phoenix are running 2 7/8" bs but running a 1/2" spacer and NO grinding...I wonder what the best way is?

tally do you have any other pics besides yoru sig picture?
