I know for a fact that the HKS Circle Earth Kit works wonders for increasing the efficiency of the electrical systems in a car. As for other grounding kits, I'm only familiar with the HKS Circle Earth.
Another add-on that I am planning adding is the HKS Twin Power DLI. Its a distribution enhancer thats supposed to increase HP by about 5-10.
Check them out.
