hyperground is a namebrand aftermarket grounding system for your car, it just allows for a better ground than stock. it helps you get the most from your ignition, charging,etc. systems. as you probably know electricity is no good without a good ground. anyway it does help, but is expensive. there is a member if I remember correctly who made his own up and he claimed it worked good. i'm guessing it probably cost about 20 bucks to make as opposed to i think like 125 to buy it. all it is is like 4 gauge amp power cable with connectors on it.
here is a link to one made by HKS and one made by Spoon
