I forget your car is not lowered, so if 18x8.5" ET13 did not rub, I think the 17x8" ET5 should be okay on your car; you may not like how far out it sticks, though. And what diameter tire on the 18?Thanks. 5mm was my other choice to front. I had 8.5x18 ET13, it did not rub. 8" et20 with 15mm spacer comes 2mm more out, is it that close?
EDIT: You mean with Mitos rub?
No I didn't mean Mitos, somehow those fit like a glove. I'm referring to these pictures:
