Grounding kits are not something new. These have been around for a long time and they are proven to work very well. Some friends of mine had tested the effectiveness of the additional grounding with a before and after test on a stage 2 STI on their Mustang dyno. They measured 2 additional horsepower after adding a grounding kit with 6 added grounding wires. I have been using a 6 wire grounding kit for 3 years. I have also not had and negative battery terminal corrosion since adding the additional grounding. Most cars are under-grounded from the factory and will benefit from a properly executed grounding kit! Nice job on yours OP.
