has any one tried the grounding wires kit on a 05-06 gt?? do they really work as advertised?? (better gas mileage, hp and lb increase, sound quality, etc)
i have seen those kits, but prices vary extremely, $115 to $40 to $14.
by the way just lowered my car today will upload pics soon.
From what I have read, so take it for what its worth, those kits do insignificantly little if nothing for our cars. The only group that see a benefit are the tuners, and again from what I have read, and even then only the cars that have a somewhat poor electrical system will regain stock power that was lost due to the subpar system.
