can anyone tell me the best offset for 18's lowered on a 1.5 in drop for an xb. thanks.

with a mild drop like that..
u can run a 20mm offset in rear if u rolled ur fenders a lil.
and about a 25 in front

all depends on the look yer goin for. staggered , popped out? all that jazz

i have the same Q. I want the wheel straight as possible, not toed in or out. And what's the most rubber i can put on it without rubbing the wells at all.
