I'd drop it MINIMALLY just to reduce the wheel well gap. Also, lowering the car a bit gives the visual impression of the car being slightly longer/sleeker, especially with the windows tinted. Depending on your miles, I'd consider replacing your original shocks all around with OEM factory sport package shocks and an Eibach Pro springs..which will drop it an inch or slightly less. If those are 18's, you should have no rubbing issues. If those are 20's, not so sure.
Beyond that, a LSE kit. And thats it. No hood scoops, fake chrome vents on the sides of the fenders.
Less..can be more.
