Congrats on your 2010 GT...sounds like a sharp car, post some pics!
Since you got lowering out of the way (which is huge), I'd look into some performance mods. Start with exhaust, a CAI, taller gears, and a tune...that should net you a few hp's. (gears won't add hp, but provide better acceleration and launches)
If that's not enough, you can look into some beefier internals and/or a power adder ~ supercharger, turbo, nitrous
You could also do appearance mods to the interior and exterior to dress up your stang. There are tons of options available for the 2010's, so there's no issue making it look hot.
