Yup, its between 2 and 2.2 inches in the back, it will max out the stock camber but only by a small bit. still, its the lowest you can go before 1.having to get adjustable rear arms or 2. get used to Omni Camber in the back and having to get new tires every year. 3SXperformance.com has alot of good spring you can use to lower it.
as far as more mods, have you seen the Bomex front lip? its nice, Nitrogun has one and it looks so freaking sweet. check it out:

also the carbon hood would be cool, since you have a moon roof check out the carbon roof cover at 3SX, the stickers I would vote against but it depends on your imagination, If you can come up with something unique and imaginative then yeah. other then that I cant think of much else, these cars are good looking outta the box.
