I'v just finnished fitting my grounding kit,I bought the seven wire kit I have the auto,and bolted #7 to the side of the gearbox It supposedly shiftes smoother, I just took it out for a run and erm whats all the fuss about....I quite honestly couldnt tell any difference, my car idled pretty smooth before I fitted the kit so I couldnt tell any difference there, maybe there is a difference at higher speeds ( I was in traffic so I couldnt open her up ) as far as a smoother gear change......the jurys still out on that one.

I installed my Insaneamine 5 wire kit today .

 

There's a current minor debate on a sister Z forum about the benefits of the grounding kits. Most agree about the underhood aesthetics improvement, however, it's ~ 50/50 on the "perceived and dynoed" results. So far, inconclusive. IMHO, the improvements can't be measured with any certainty at the wheel on a standard dyno - too many uncontrolled variables. This forum tends to be more data driven so I'm open to hearing others thoughts.

 

I've had mine for about a year now, was one of the first mods I did. The idle did feel smoother after installation. Other than that, I noticed nothing else. BTW, it was the five wire Insaneamine kit on a 6MT. If I had it to do over again, I still would.

i installed a 5 wire kit too. I did feel a smoother idle but nothing other than that.

 

i installed mine last week, and its a smoother idle, and for $65 bucks why not.

 

I gained 3 mpg after about two weeks and definitely noticed smoother idle...

 

3mpg and how many miles were on the car at the time. could be explained by breaking the engine in, or even different driving style; possibly different in a subconcious way where you were trying to drive very smooth because of you wanted to feel the improvment of the grounding kit.

yeah, might be a bunch of psycho babble.

either way, I got mine as my first mod; home made. considered it a bonding session with my new car. a good hour or 2 on a job I could easily do myself with the car. if it helped in some way(that I really cant feel or notice) great. otherwise it just made the engine pretty and I had fun.

 

yeaaaah. i pretty much got mine for looks.

 

HAHA... I was kinda thinking the same thing... except my dollar figure was more like 20 bucks... i guess that's why I haven't gotten them yet....

ARES: Great post... this is what it's all about.
