That $h!T is heavy and is dead weight. Inside the car may be a tad bit louder, but these are not hyundias, porsche uses thick metal and/or uses enough undercoating to negate the sound enough. And nevermind if you have a window leak that you dont know about, the micro foam that they use acts like a sponge in the presence of water and then gets real heavy.
If you are talking about the tar pads under the seats and footwells, they are good for about 7 lbs a side
