Well, my current setup is absolutely horrible, but I have an s13. I'm really running at my fitment limit. I have some 17x7(.5) +40... that's right, 40. They shouldn't even fit. Well... I had a set of 225's on the front, and one side rubbed a bit of coating of my coilover spring lol. Now, I'm running a set of 215/45 kuhmos w/noooo problem, and in the rear, I have 235/45 potenzas, but I could probably fit a 245 or something. I'm on tein HE's.
Okay. You have a bunch of options when it comes to offsets, and etc. Your prolly running 4 lug, so that cuts your choices by like 80% lol.
Here's your 4 lug choices from the 5zigen website for FN's:
17x7 +35 They recommend this for s13 front
17x8 +35 They recommend this for s13 rear
17x9 +20 They recommend this for s13 and s14
I do not like either the 17x7 or 17x8, because of the horrible offset, sunken ship style. However, 17x9 is a little over the top, however will fit with camber, rolling, and/or pulling, and stretched tire if you want real man wheels lol.
You can get the 17x7's and 17x8 to fit more flushly with a wheelspacer, but I don't like wheel spacers, because they are supposed to be unsafe, but some D1 cars run them, Nascars I beleive, along with all kinds of other cars in the motorsports world, so take this with a grain of salt.
If you really want the best wheel variety, then go 5 lug.
