I currently have 4 kits available for the G35 coupe.
I can have kits made for your 350Zs too, if anybody is interested.
What do they do?
Smoother, faster shifts (5AT), especially in DS mode.Increased powerIncreased Fuel economyBrighter headlightsCleaner sound from your speakers
My 6mt coupe feels a little torquier, accelerates faster, and my non-bose sound system sounds cleaner. Still waiting on the new engine to measure fuel savings.
The grounding systems can be made for performance or performance and show.
They work by providing a super low impedence return path for many of the engine electronics which means less noise and faster signals.
Take a look at my thread in the Fab Marketplace and let me know if you're interested in a kit.
Prices for the 350Z should be comparable or slightly lower than for the G35 coupe.
