ok so i want to order some CCW SP500 wheels and i want 18x11.5 for the rear and 18x8.5 for the front. what offset/backspacing should i get to tuck these in nicely?

On a Camaro those will not tuck at all, on a Firebird , they should since the wheel well is a tad wider.

CCW, should know what offset to provide. I'm gonna guess around 55 mm.

well i know for a fact 11.5 will be perfect on a camaro cause i had a set w 315s and got rid of them without measuring the backspacing before i let them go.. however they were 17x11.5....im going now with 18x11.5....maybe i shouldnt have said tuck more like flush with the fender lip? i know with the 315 bfg DRs i had the outside tire wall was almost exactly flush with the fender lip just a tad bit tucked in more...wish i knew what the offset was

What were your previous wheels? There aren't too many 17x11.5's, but plenty of 17x11's.

I have 17x11.5s on my camaro and it is possible to get them under the fender, you just need a tad narrower 315

oh ya nittos would prob be perfect but i had 17x11.5 with the wider bfg drag radials 315 and i loved those for the price. i guess ill just call CCW im just worried they recommend a offset that wont be the fit i used to have...
