Simple question. I was wondering if groundsing kit really worked and which kind is the best one to get

Did you try the search tab at the top?

To answer your question, they work, but they don't add any noticeable performance.

+ 1 SEARCH!

depends on what you mean when you say "do they work?" horsepower: not really, smoother electrical system: yes

Unless your OEM ground wiring is rusted out and the car is falling apart, grounding kits are a waste of money. You will find no objective proof of any performance gains, or that the car runs smoother, or whatever else people will write on the internet. The only people associated with grounding kits AND that understand electrical systems, are selling them to others. I'm sure as the sun will rise tomorrow that someone will come behind me and claim some benefit from these, but besides looking like an octopus has invaded your engine compartment, they are a waste of money.

TY for summing up my thoughts exactly. I'm an electrician by profession and I still can't believe people buy into them and praise them. They're just as useful as a "+25 HP ULTRA PERFORMANCE CHIP" (resistor, aka a piece of ceramic that converts electrical energy into heat and then dissipates that heat) or a "TURBONATOR +15 MPG."

only plus side to them is an engine dress-up. They can add a show quality under your hood. If grounding wires gained hp, i would connect them to every bolt.

what about the sun-auto hyper voltage system kit?
it says "12.5 hp gain" on the website, is this also bull***t or legit

That would be cow dung. 1hp TOPS. If that.

I've got that kit on my 04 G coupe. . .doesn't do anything for horsepower or torque .. .whichever car they tested it on/compared it to must have had a shitty grounding system to begin with. . .

Headlights are brighter and same with the gauges . . .that's about it . . .you can spend your money better somewhere else . . .

I don't buy it about the lights either. The decrease in ground resistance over the OEM cables is so small that there could be no discernible improvement in your lighting. As long as they look brighter to you, that's all that counts. Same goes for the horsepower claims of the Sun system. If you think that's money well spent, go for it!
