Right now, with my tokico drop (with tokico illuminas), there's not much space at all between the tire and the strut, so my question is if I swap out my tokico springs for the s-tech's (1.5" compared to 2.2" in front), will I have any problems (rubbing)?

Wheels are 18x8 with 235/40 tires.

 

no you won't rub, i've got 245/40/18 with the S-tech's and i've never rubbed

i'm 18x8 too
