Earth Harness Systems, Worthwhile or not?
 

I'm looking at the Earth Harness systems (EG The Cusco one), and wondering what real/measurable benefits there are to fitting one, or is it just more engine bay bling that adds no real value.

No right or wrong answers here, just looking for opinions (although data would be good).

maybe if you had a big system in the car with an HO alt... the big 3 should serve the same purpose for cheaper.

Depends on how good the factory earth is. Most late model cars are pretty good.
I put one on my old AE111 Levin & it made quiet a big difference (higher voltage reading on the SAFCII). Put one on the Altezza & it didn't seem to make any noticeable difference. If you're going to fit one I wouldn't spend too much.
