Like I said before, the wrx isn't a high speed car. No offense, but I think those of you who say your wrx is great at high speeds (even though we drive the same car lol) probably haven't experienced a car that is truly great at high speeds. Compared to a Cavalier, yes, the wrx is astounding at high speeds. As good as an m3 or 944 (old) no.
I will say that even with just lowering springs on my wrx, it was much improved on the highway. Now I'm back to stock and loving it.
