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.

 

If your running several add-on electronics, ie gauges, amps, xm radio, intercooler sprayer, etc., having the car grounded above and beyond factory specs sure won't hurt things. Just do it your self for around 10 bucks.

 

if it made expressos id get it

otherwise no, not worth it.
