yea man, i have one on mine. Im the one with the crystal grey and gold rims that was drivin with you all last thurs. remember?Anyway, i mean at 5 am after you've been workin on your car putting new stuff on and then you take a test drive.... to make a long story short, i noticed a far amount differences. i noticed my radio was louder and all the controls for it worked nicer like the bass and mids and stuff. i also noticed that my gauges lighted up really bright. i think my car drives a little smoother. what i mean by this is that when i shift b/t gears it doesnt seem to be as notchy. so i noticed some stuff. oh, my HIDs dont seem as dim. i got mine from k2motor.com and it was 30 i think? just meet me this weekend man.
