"INFOCircular Grounding System - By utilizing a 24 karat gold plated distribution block and multiple grounding points, improved idle and drivability are often obtained as the additional grounding points equalize resistance and voltage between various ground points. Each 8 guage spiral twined cable is wrapped with signature HKS purple plastic to protect and add color to the Circle Earth System. Vehicle specific kits included pre-measured cable lengths and distribution blocks.

anyone know if these are worth it?? They are $112 shipped and anyone can get on this deal. Just post here and I'll pm you the guy's e-mail address that is sellin em. I think I'm going to order a set myself. The dynosheets said cars installed with em installed made a difference of 4 hp.

first on what type of engine are you putting the grounding system on?

yeah but this kit works better on the sr20 but yeah I don't see why you shouldn't buy it.

Just make your on its not hard your not gaining any horsepower your just getting back what youve lost over the years

dude i have it on my S13, Sr20 and sorry ... no difference what so ever!!!!
(i put them in because the original ground wiers were just too old and used!)
BTW it is a good investment, especially if u want a clean car look. but for performance, its just not that great.

I want it mainly for maintenance, not performance. Since i got a rough idle it should help

When you say there is no diffrence is that dyno proven? Or butt dyno?

rough idle? changing your spark plugs to ngk iridium. i think that'll do more for the idle than the ground system. or get them both. the mod doesn't strike me as bein all that useful tho unless your car has more than 10 years and 150k miles on it.

make your own grounding kit

I plan to do that. Thanks for the advice

hey frostbyte i did not dyno it. (it is a $100 for dyno here!) what i know is that after i instaled the ground kit, Iradium plugs, ignistion ,and a Z AFM. i gained a 16 hp to the wheels. ??? how much of that is from the ground kit?? i don't know. keep in mined my original lines were veary old .

Buy some welding cable and do it yourself. $100 is a lot for some pre-terminaled wires.

Yeah, but they're purple and all, they look nice, and they come with instructions!! lol

You do have a point. The purple is "fabulous" and dyno proven to add 20hp. If you use it in conjunction with other colored hoses and wires, it is worth 45hp.lol
