My car is lowered a good 2" in the front, and about 1.5" in the rear giving it a good stance. My car is not daily driven, and the only time I've had it scrape was going over massive speed bumps, or steep inclines.
I am very careful when I drive with an eye out on the road ahead of me to avoid any obstacles.
I have un-coated Pacesetter LTs, 3" Off Road Y-pipe, and a 3" magnaflow with a cut-out and I absolutely love the sound it gives me. Its very mellow through the muffler, and when I open my cut-out I get that obnoxiously loud sound that makes every bone in your body vibrate.
Heres an idea of my ground clearance:
