15x10 7.5" rear

3.5" are 1.75" fronts

gona have to upgrade the studs and do some grinding on the calipers

edit/update: thats what i had when i was looking for rims for my camaro but wanted to double check since i wasnt sure if lt1/ls1 brakes were different. I did some searching and found this to confirm on a ls1,

"I finally finished up installing my Prostars 15x10 7.5" backspace on my car tonight. You will need to:

Grind rear calipers down about 1/4" so the rims don't rub on the calipers

Install 3.25" ARP wheel studs so you can properly tighten the wheels

Use shank style open ended lug nuts of you want to drag race with them

Also i used a 5/16" wheel spacer for a little extra clearance

There is no inner fender bending, hammering necessary if you do what i did. Hope this info helps out..."
