I got a S13 (90 240SX). I want to get some wheel for it. But I am stumped right now about what size to get and offset. I did the 5 lug conversion and front z32 calipers. I was looking at LE37T in F: 18x8.5 +30 R: 18x9.5 +35. Will these actually fit without any problems?

 

For the fronts...if your worried bout clearing your caliper, the +30mm should work. Its your struts im worried bout if its lowered. For the Rear, 9.5 width with only +35 wont work cuz for that width your gonna need wide a** tires. If you can get something lower offset *23 or less* That would be perfect plus youll love the look. I know somebody whos running 18x10/295 in the rear, and i believe his running 13mm offsets.

 

offset has nothing to do with clearing calipers, its spoke design. but yes, go for a lower offset. you might stick out though.

 

What you recommend for tire size for the 18x8.5 and 18x9.5?

 

with 18's on a stock KA, you are going to have alot of wieght to overcome... Yet IF that Gangsta look is what you want, I would
run with 18x8 225/45/ on front with +32, 18x9 235/40or45 on back with +35. Anything more may be Toooo tight for the suspension.
P.S. Hope your suspension is NEW or at least newer than 30K, becuase the OEM will be crap for your tires due to worn out.
