hey, ive got 5zigen 18x9.5 +12 rims with 265/35/18 rubber, no scrubbing issues @ all. With coilovers i've drop it by an inch or so, can drop it more if i wanted , but dont wanna scrape my lip.
If you are lookin for a set of springs, you could go for Tein springs they cost round $250 for a set of four. Or also check Sydneykids group buy for whiteline springs.
Your std rims/tyres are worth $1000 and up.
What type of rims u looking at?
