since i totaly forgot about this thread since the op is a complete retard and wont roll his fenders. those pics you posted are no 17x8 -20.... sorry but they arent they fit weak as hell on that s13. you can run 17x9 +20 with no roll but why risk choping up your tires. you cant be low with that and if you are you will need to run neg camber end of story.
The wheels I posted are 17x9 +20, all around. No chopping tires, no rubbing fenders. And I have a roll, but that's it.
And second of all, dont you have like 17x8 +35 fucking sportmax on your car?
