I am lowered on a KW spring(1.75") Roush strut/shock combo, and I rub pretty good. I had 18" Konigs with a Nitto 215/35-18...actually rubbed a tad bit less than my 17" 215/45-17 combo I have on there now. So I would say if you go with a 215/35-18, it would look just right with that kit.
Edit:I have a 01 ZX3 btw
