+38 eh? Gah, now I have to go and question the three mag shops that told me +40.....i have the 20's they only rub the plastic when the wheel is turned all the way... my offset is +38 the correct offset is +42... my wheels are 7 1/2 inches wide...
What offset are your 18's?At STD ride height I run 18's with no scraping at all, however when the springs go in next week I'm sure that'll change.
