is this a good idea

I've read a couple places that they actually do help a little bit (minimal).
I'm interested to find out also.

i heard that by grounding your alternator, your actually making it worse for your car. Im not sure if its true or how it would make it worse but any advices would help. I too am thinking about buying this kit but not sure what i will really gain.
