FWIW, I'm running 9.5" wide wheels (ET35) with 265/35-18s and with an LCI Sport package car I've gotten zero rubbing. And short of putting a bunch of fat guys in the back I've done everything I can to TRY to get them to rub. I'm now thinking of putting these up front and getting something wider for the rear.
I really wish Apex offered an ARC-8 in an 18x10 or 18x10.5 with a higher offset! Won't y'all think of us LCI guys??
