I've wanted to lower mine, but have held back because I don't want to mess up the high speed stability of the car.
I've not yet been to "Where Life Begins" and I've heard that lowering the back can cause instabilities up there where the air is a lot denser. Remember that "Flat Spin" in the movie Top Gun? It would surely suck to do something similar to that on the freeway at warp 1.8.
Besides, I scrape the front air dam getting out of my driveway now with the car at stock height. If I lower it even an inch in the front I might not be able to get out of my driveway without leaving parts behind.
And some day I might actually have to go over a speed bump in a parking lot and I don't want to leave my exhaust system on that speed bump.
