The stud pattern are different between skyline or even nissan to subaru, it's 5x114.3 and 5x100, so it wont fit unless you change the studs pattern, 8.5 width of 18's wheels fit nicely without scrubing to my05 sti on standard height, however i've seen my02 fitted with 17x9,5 advan rg as you've seen the jun sti ra, but you'll have to roll the guard make it a bit wider and of course you must have coilover, and proper wheels offsets / tyres setup. it looks nice though
