For those of you with 18s on 6th gen 4 cylinders, how much acceleration did you lose like for example when you sped up on an overpass to get on to the freeway? I wanted 17s because I didn't want to hurt perforance to much since my car is slow already. I do a lot of freeway driving and always have to accelerate on to the freeway. I saw some 18s that were REALLY nice and I just fell in love with them.h:
