I am looking to purchase some rims for my SC. The size that I am looking at is
18x9 +22 (F)
18x10 +22 (R)

How well would these fit my car?

What is the widest set up I can have for the rear and not rub?

I looked thru the wheel fitment thread and really didnt find anyone around this setup.

 

I believe mongolkhan is/was running 18x10 +22 front and back...he posted a picture of his Advan's clearing brembo bbk awhile back...

Roo also went with a wider rear, I forget the exact specs, but i think its 18x11 +26?

anyway, those sizes are nice...18x9.5 +22 and 18x10.5 +22 would be 350z, G35 fitment...and you would need to shave/roll and pull your fenders for those to work. A member here, I believe BMSport, has Volk's in that fitment...

 

if you ready to shave / roll / pull fenders and run negative camber, then go for it. Please be advised that a amatuer with a fender rolling tool will buckle the fender which leads to a new fender and paint etc etc.

Make sure you are up to the task and deal with experienced individuals.
