Stillen 370Z / G37 Grounding Kit

Pleased with the modest performance improvement and clarity in speaker system.

I honestly thought it was a gimmick, but after installing, I had a very noticeable quicker throttle response and gear shifts, and my interior LEDs I installed use to show very dimly at night which bothered me a lot. But now they do not show a dim light at all and turns off completely as intended. I guess having more grounding actually helps take some of the load off the engine and other connected components that use electricity. Definitely recommend, especially if adding more power draws (chargers., aux lights, navi, subwoofers, etc.) to your G!

This kit absolutely helped my 2015 q60 7at shift smoother and faster, im talking about a night and day difference. HOWEVER I was very disappointed in the instructions. I can see this being a very intimidating install for the average "once a month weekend wrencher", the lack of color illustrations and broad descriptions are very lazy. I also have an issue that the only colors are red and silver(silver was out of stock at the time I ordered), this should come in black for obvious reasons seeing as it is a GROUNDING KIT.

100% recommended. Good Quality

I was skeptical if this would do anything but decided to try it. For me it WORKED! My G seems to shift better and doesn’t seem to lag as much. The G is stock with no tune. If you’re tuned it might not be as noticeable but stock I can tell a difference. Directions were good. Install was easy. The part seemed like good quality. Shipping was fast. So far I haven’t noticed any problems with the charging system so Yay! I would buy this part again.

I have a bone stock 2012 G37 Journey Sedan 7AT. I love driving the car in manual mode, but the shift delay can be annoying. I read that the grounding kit can help reduce shift times in manual mode. However, I was on the fence about getting it because there seemed to be an even split of opinions as to whether it does anything or not. I suppose I got lucky, because it actually made noticeable changes. The car shifts significantly faster in manual mode; if I had to quantify it, I'd say between 50% and 60% faster. The Bose sound systems sounds improved all around as well. Bass is much harder, and the mids are louder. The install was straight forward. It only took about an hour (other than the trip to the store to get a new battery terminal screw because the end of mine was stripped). As for the negatives... There aren't many. I noticed that automatic window on the driver door stopped worked to go up (works to go down though). I will also point out that the pictures in the directions are almost no help. They're black and white and the resolution is so low, it's hard to make out what is going on. No worries, there are a few decent videos online that helped. Overall, I'm very happy with the grounding kit and highly recommend it.

Would definitely recommend

Easy install comes with instructions don’t really notice a difference but I know more grounding points for electrical systems is always better so I’m happy with it.

Install took about a little over a hour not too hard for the average mechanic. Overall made the audio louder, shift speed quicker, and idle smoother. 10/10 great product for my G37 7at
