Grounding Kit for 370Z
 

I was enlightened by the prospect of reading about the benefits of installing a grounding kit. According the Stillen website, the benefits including the following.

1. Ensures Proper Ground to Sensors and Computers to Prevent Performance Loss.

2. Featuring 8-Gauge Copper Wire, Gold Plated Connectors and 4-Gauge and 8-Gauge Ring Connectors.

3. Improve Shifting and Reduce Shift Lag on Automatic Vehicles

4. Reduces the loss of HP and Torque.

As I have a 7AT, I am of course very interested in benefit No. 3 above.

I am having a difficult time wrapping my head around this one and understanding these benefits? Would appreciate any feedback if in fact these claims are true. These grounding kits retail for less than $100.00. If true, it would have to be the best bang for the buck Mod there is, right?

Someone help me to understand this better. :icon14: Thanks.

Your vehicle is supplied with perfectly acceptable wiring, and only reason to install something like this is for looks.

If you wound up with a situation in which wiring had corroded, etc, enough that wire impedance became a concern....you would be best served replacing it with wiring purchased from Home Depot for $12.

Some people report better performance, but I'm guessing placebo effect. If you want one of these, go buy wire, ends and heat shrink tubing and make your own for a fraction of the cost.

Does your car start? Do your headlights come on? Does your radio work? Interior lights work? If so, car is already "grounded." Save your money. Their "benefits" have no foundation in reality.

I have the lines and a 7at. It does #3 for sure. The rest I can't tell much difference. Was it worth me spending $100?. Well I didn't have to size and crimp wire all day long... But for about $30 and a couple h ours of your day you can do the same thing. Transmission response is NOT placebo though. AT shifts faster with ground kit.

don't do it.

IF your wiring has deteriorated over the years, a grounding kit might have some value. If you have installed a larger amplifier for your stereo, a grounding kit might do some good. If you have installed any other high-current devices (eg, big fuel pump), a grounding kit might help. Otherwise, it's pretty much snake oil.

I can see no way that it would help the 7AT with shifting - unless you have a grounding problem to start with. If you have a grounding problem, just install a larger ground wire to the transmission (no need to do the whole car).

fixed...

I agree on the no way to help with shifting. Yet on the grounding portion I disagree. I don't have the magazine with me, but grounding kits do actually work. I read an article about one they had on a FRS. They did dyno pulls for every part of the grounding kit they put on the vehicle, and in the end 2 grand later it gained 6whp and 4lbs of tq. Which obviously is retarded and the magazine boasted it was such a great gain from something so simple. Simple yes cost affective no if buying one that is preset. As far as aesthetics I wouldn't say it does much as whatever color you choose will now be laying around in your engine bay and people will say hey what are those colored wires for? This can go back and forth and I am sure after I post this more people will chime in. You may or may not see some benefits but make sure you are using the grounding points they use with the stillen kit and it would be cheaper to make your own. Best way to put this topic to rest is do a baseline dyno, install kit and run her again. Good luck with purchase.

Don't waste your money on this. If you must have this go to your local hardware store and get wiring shrink tubing and do a nice DIY. You Z is perfectly grounded.

Well within the margin of error on a dyno. Dyno your car every day for a week and let me know what happens

also dont forget the garden trim and the ballcockshank washer. :tup: :ugh:

:p
