hey
here are some of my opinions .. i'd go with either 17, or 18" rims first .. then lower the car, get coilovers/springs and aftermarket struts ... + a camber kit .. then the basic bolt ons (cat back exhaust, hi flo cat, headers, cam gears, flywheel .. etc ) then CF hood .. all lighting stuff ( angel eye headlights, HID kit, hyper white bulbs , clear corners ) should be last ...
then maybe a cf hood ?? short throw ? centerforce dual friction clutch? something in that area ...
i got eibach sport lines and koni 5 way. adj. struts and 17" 5zigen rims with kuhmo's (lo-pros) and my car rides great .. and for how long you should drive your car before you lower it because you don't want it scratched, i still don't understand that because your not making your vehicle wider or soemthing and that doesnt make you prone to hit something .. so i dont know where your trying to go with that .. whatever, just my $.02
