I did this on my G35 Coupe...
I had a 5AT G35 Coupe and completed a DIY grounding kit mod. I read on G35DRIVER that it would speed up and/or smooth the auto tranny shifter-it was right.
The car shifter MUCH smoother and idled better. Was there was a hp gain? I doubt it. I was happy though. My goal was to improve the auto tranny responsiveness.
I'm not sure if there's a real advantage on doing this ona 6MT w/no crazy electrical add-ons (e.g., aftermarket stereo), but it certainly cannot hurt!

I upgraded the stock groundings, the one on negative battery, and the two at the alternator I think. didn't notice anything different. I have a 500 watt subwoofer amp and 75x2 component amp with a pioneer headunit. My alpine amp was still saying it was at 14.1 volts, which is what it started at before.

Great Job ... People whine about the neccessity of a ground kit, But its needed. OEM is ALWAYS minimal when it comes to grounds. Its just good insurance...It wont make you go faster and chances are you will feel no difference but it may save you a fried system some day.
Great connectors, I have a drawer fulll of them, always scrape all the paint off the connecting point and preferably use a bolt, Nut and Lockwasher.
As far as grounding points...... Battery Ground to Body AND Frame.....Engine to Battery Ground, Body and Frame are the most important.
There is also a product called Liquid Electricians tape that comes in all colors, that can be dabbed on the wire to connector connection to seal it

Hi guys (and gals)~ Just a quick update; Here's some pics of an upgrade I did this weekend to finish the diy grounding kit. This is what they call "The Big Three", which consists of Pos Batt ---> Alt ---> Chassis ---> Neg Batt.
To complete my diy engine grounding kit, I installed (1) 2 AWG wire from the Pos Batt to the Alternator, and (2) lengths of 2 AWG from the Neg Batt to the chassis. I left the stock wiring in place and simply added to it. I needed this mainly because my amps were taxing the stock electrical system to the point of making my lights go dim when the amps hit...
This upgrade completely fixed the problemo. My volt gauge never goes below 14v now, no matter what I throw at it. And my Caps now read a constant 13.8v. The wiring upgrade probably doesn't hurt perfomance either... Ummm... Placebo effect on that one?? Maybe~ ;-)
I bought the copper crimp connectors, shrink tube, and wire at Autozone. The wire was $1.98 a foot. I used about six feet.
Edit: Forgot to mention that unlike the Ground upgrades, you ***MUST*** disconnect the battery when you're upgrading the Batt + to Alternator. If you don't... Well... You're a braver soul than I am~ :-)

Nice work on the upgrade...
Is is necessary to disconnect the negative side of the battery before you install a grounding kit? I was looking to do put one on myself because i have an upgraded audio setup and have been experiencing weaker starts from my Z. Wondering if you should disconnect the neg. terminal side of the battery...

I chose to use the factory connection point on the Pos Batt termainal, since it's already fused. I couldn't verify that the other mounting point next to it was fused (or if so what amperage), so I didn't use it.

Especially considering the amount of electronic gadgetry we throw into them.
