Do suspension to lower the car 1.5 - 2" (Ground Controls / AGX's are a very popular setup... will run you about $800 or so, depending on where you buy, but it is well worth it. Cheaper setups like AGX's and Eibach/H&R springs are also good to use, a little cheaper at about $550. The latter will work for appearance just fine). Next, find a nice set of wheels to roll on. Some lite-weight 16's will to the trick. Everything is relative. If you want a great setup, it will cost you. Some people choose the cheapest parts and then complain their ride sucks. If you just want "show", go cheap, but you'll bounce everywhere. If you plan to "use" your suspension, you might want to think of a higher quality setup. Also, tint is a must. Just don't doo-dad your car up with stickers and trinkets to make it look fast. LOL
