the fronts are horrible for noise.. as a matter of fact, i ditched my MT's because of them!! The rears are VERY nice. I can leave the windows cracked, or even part way down with only minor noise. The sunroof is 4 or 5 times louder then the rears. The fronts just arn't worth it on the highway. (to bad is looks getto with only the rears).. I only use the fronts for parking.. but the 4 are great on a hot day. I normally leave them cracked every time i park.cuts down on the frose in the morning also.. there is a stripe 2 or 3 inches tall along the top that is clear, while the rest of the window is frosted.
