Square Wheel & Tire Setup Questions
So I'm looking to pick up some RPF1's in 18x10.5 all the way around. The offset will be +15 all the way around as well. I want to add a 15 mm spacer in the rear, to bring the offset to +0 for a more aggressive stance. Should I add a spacer up front as well? I'm looking for a pretty aggressive stance, I'll be lowering on some coils soon as well.
My question to you guys is what tire sizes should I run? I have already rolled my fenders all the way around. But is pulling necessary? I'm not looking to do some crazy fender work just to get these to fit.
From searching around this is what I got:
18x10.5 +15 with a 245/40 in the front.
18x10.5 +0 with a 245/40 in the rear.
Does this sound okay? If you think i should add a spacer up front please give a tire spec! As well if you have other recommendations
Thanks

18x10.5 +15
18x10.5 +15/spacer -0
245/40 front/rear
roll fenders
few degrees camber and your set
a few members on this site with similar set ups below
if members are running 13 wide on stock body,you shouldnt have a problem with 10.5
EDIT:silverstone is actually 18x10.5 +15/ 18x10.5 +15/spacer 20mm and tires 265/35 all around but you get the idea

This is the exact set up I was looking at. I didn't know if his fenders were pulled though. I have rear camber arms already, do I need to get camber arms for the front as well? Or will stock arms allow me to set the right amount of camber that I need?
Will I still have full range of turning with 245/40? or should I go with a 35 series tire?
Still learning, trying my best. Thanks everybody!

think this guy fenders are just rolled stick with 245/40 if you drop to a 35 you gonna have to lower even more to get rid of that little gap and you can possibly get away with stock arms look up my enkei theard or the 18inch wheel thread they have alot of similar set ups just have to search thru a few pages

Ordered my 245/40/18 tires today for a great deal from discount tires! I'm going to order a 20 mm spacer instead of a 15 to bring the offset to -5 in the rear. I want it more aggressive. I won't rub will I?

if they are...they are very SLIGHTLY pulled. i think you'll be fine with a roll and some neg camber since you're running a 245/40
Yeah that's what I thought. I wish he had more pictures but those were all the pictures I could find ANYWHERE. I remember him selling his Z in my area, but I never got the chance to ask him. 245/40 is pretty skinny I don't think it will rub. But maybe I should measure first. Idk I want to order my spacers now, so I don't have to pay for alignment twice.
