Thread: Biggest allowable rim size......

Reviving an old thread. So i have an 05 GTP Comp G. Just threw 3k at the suspension and redid everything, adding in zzp coilovers, their biggest sway bars front and back converting to the control arm endlinks, and lowered the car ( will raise if need be ) but i want to change the rims and for right now im looking at used and found a set for a good price. But they are 18x10. Unsure of the offset. Chances of them fitting without do fender work?
