earthing kit on 98 gtb limited

[rfrbwags]

i have a unmodified 98 gtb limited with 57000km and over the past few months i have read in numerous forums that
a good earthing kit can work wonders on all subaru(particularly early gen) vehicles as they were fairly poorly earthed from factory.i just bought a (not yet arrived) 5 wire,9mm grounding kit with gold plated ends to go on my wagon.
I hear they can prolong all electrics,fuel system etc,and help with accurate ecu funtioning aswel as brighter headlights and louder/clearer stereo,one australian company claims they gained 4wkw on a V4 JDM STi so i thought what the hell....
If anyone has any tips/advice id be glad to hear what you have to say.
Cheers

Tips? Well if your factory grounding system is poor, or corroded then yes it will help a lot. On the GTBs a good earthing system also helps eliminate the VOD issue between turbos as well.

You don't MAKE extra power, but you gain it back.
