I am about to get the 18 inch BBS RG-Rs for my S and wanted to find out if my car will rub since it lowered about 1.5 inches. The offset that tirerack offers is 50 for front and 53 for rear in 7.5 front and 8.5 rear.

Thank you in advance for all the help

 

They will probably rub with a 1.5" drop, my 18" RG-R's rubbed a little up front with a 1" drop. It also depends on the tire size and sidewall shape.

Running 17" Volks now, no rubbing.
