Wheel offset
What kind of wheel offset should I look at for a 2002 Z06 with rear fender flares? Wheels size would be looking at about a 19x12 or 19x12.5

it's pretty easy to figure out.but need to know how wide the flare is.if you start with a factory z06 wheel and convert the offset to backspace that will give you a starting point.a 10.5" wheel with 56 offset has 7.95 backspace.with flares you want all the extra width of the wheel added to the outside of the wheel.so if you have a 2" flare and want 2" wider wheels you would want a 12.5" wheel with 7.95" backspace.that gives the same wheel to fender as factory.now just use an online calculator to convert backspace to offset.so a 12.5" wheel with 7.95 backspace has an offset of 30.48mm.
if i was doing a 2" flare i would go with a 13" wheel with 30mm offset.with the extra 1/2" of width and that offset it would put about 1/8" more wheel on the inside and about 3/8" of wheel to the outside which would sit pretty much flush with the fender.
