i have the same car..exccept 4 cy.. but i have 18" (enkei rs5) on it and i live in orange county Ny (the sticks almost) but i have a fair share of potholes and they have been holding up fine.. of course i know the roads and if u know where the biggest holes r def SLOW down. but other than that u should be fine.. plus 18" look soo much nicer the fit the entire wheelwell ...personally i think 17" look soo small on our car...
cccan u see what i mean....
