I have possibly found some rims and they are 20x10 in the rear and 20x8.5 in the front. I was wondering if there is a chance that they'll scrub the inside wall or not? and i was also thinking of dropping it 1"-1.5". oh and btw this is an 04 G35 sedan.

 

Tire size and offset would probably help a little here. I know there are some dudes running wide wheels on sedans here that could be more help.

There's actually a thread in the picture share specifically for sedan folks w/ wide wheels:

im pretty sure 10 is about the widest you can go without having major problems.

 

you can fit the rear if its at least +40mm offset....

front if its at least +35mm offset
