I have had that same type of lip, twice on two different cars as a matter of fact. I have always thought that it looked so aggressive. From experience be very careful, as you stated already, with driveways, dips, things in the road, and parking stops. Not sure if you have springs or are lowered, but all the more reason to take your time and be extra careful. If you are not lowered, I do NOT recommend that you do. But if you want springs or coils, I strongly suggest that you remove it.
Other than that, enjoy because it looks great!!!!! Mine was CF, but the body color match looks like it was meant to be there.
