Will G6 GTP 18" wheels fit a SS/TC?

yes they will, check out hockeyman's ride

I have an ss/sc, they will fit the ss/tc with a 15mm spacer.

I can't believe you haven't sold those wheels yet. They look great on your car. If it weren't for shipping I'd pick them up.
Thanks for the accurate answer. I don't know if I am comforable with running that large of a spacer. It would be over a 1/2 inch meaning a 1/2 less of threads for the lugnuts to attach to.

you can always get larger lug studs...i'll make you a deal if you want the ones i have :)

Yeah you would definitely need longer wheel studs or a spacer that had its own studs for 15mm, even for 5mm you would lose most of the threads. Anyone have a source for longer wheels studs?
