Have an '85 Camaro, and need to know what kind of lug nuts I'll need, both thread and style, currently has 14" steel rims on it(bleh) I'm putting 16" IROC-Z rims on it, also I'm wondering if they can fit bigger tires than whats on them....I couldn't seem to find any information saying what year/package had the tire size of 215 fronts and 225 rears? Anyone know what came with that? I guess I'm wondering if they're supposed to have bigger tires then what they do.
12mm 1.5 pitch acorn, tapered, style nuts
