ground kits claim to improve hp, tq, gas milage, steady idle, throttle responce and brightness of headlights

i purchased both, the 30 dollar circle earth ground kit from ebay and the sun co. hyper ground system from sportcompactwarehouse.com. the circle earth has been installed in my dad's 1.5liter 95 mitsu mirage, and the hyper ground system went into my xa. both cars are manuals.

improvements in every claimed aspect could be felt upon installation of circle earth system. of all aspects, throttle response had the most dramatic improvement. headlight are brighter by picture comparison.

i installed the hyper ground system in the xa today. the only improvements i can note is the headlights being slightly brighter, and the idle is, now, steady as a rock. i can't be sure the throttle response or anything else is any better.

although the improvements from the hyper ground system are less noticible, i still trust that they are making the claimed differences. if you're in the market for ground wires, i, actually, recommend the HKS kit. i've come to relize that most ground kits do not differ much in performance. the way the HKS kit is set up just looks more organized.

 

Have some comparison pics?

 

coming soon!

 

those hyper ground kits are expensive... I might just get a circle earth kit. Or maybe a Happie kit...
