They said: This will help you with overall power increase. This is a grounding kit that will help overall performance. You will be able to push the power longer than a factory set up.

Any thoughts on this? it's made for the XF and only costs $60.

 

Grounding kits are pointless, they're just a placebo. The factory grounds are more than sufficient.

Unless you're running some super high power audio setup with it's own power supply you don't need to wory about a custom grounding kit.

 

I'm going to echo John's statement, don't fall for the quick Hp marketing.

 

Oh it DEF sounded to good to be true.... Just wondering about it. Thx guys!
