ACT 2015 Nissan 370Z HD/Race Sprung 6 Pad Clutch Kit
ACT NZ2-HDG6 is a ceramic 6-pad clutch kit for the Nissan 370Z with the VQ37VHR and six-speed manual, built for cars that have gone past what an organic street disc can handle: turbo and supercharger kits, nitrous, drag launches and road course heat. If your 370Z clutch slips under boost, smells after a track session or glazes after a few hard launches, this is the kit ACT builds to fix that while keeping a moderate pedal.
The kit pairs ACT's N024 Heavy Duty pressure plate with the 6250306 sprung race disc. The pressure plate uses a heat-treated diaphragm to add clamp load and reduce deflection, so pedal effort rises only modestly. The disc is 250 mm (9.8 in) with six ceramic pads on a 1 in input spline. Ceramic tolerates far more heat than organic facing, and the six-pad layout gives faster shifts. ACT keeps a spring center in the hub to damp torsional vibration from the VQ, which is what separates this disc from ACT's rigid NZ2-HDR6. ACT rates the kit at 574 ft-lb at the crank, 100 percent over the factory clutch.
The trade-off is engagement. ACT calls it aggressive, and a puck disc gives you less slip window on takeoff than an organic one. In traffic it takes a deliberate foot, and some chatter is part of the deal. ACT recommends it for high-horsepower street or race use.
Rule out hydraulics first: check fluid, bleed the system and confirm the pedal returns fully, because a release system that holds the clutch partly open will slip and overheat even a new disc. Then do a steady full-throttle pull in 4th from low rpm; rpm rising faster than road speed is slip. Our transmission slipping guide covers the road test, and shift flare vs. slip explains how to tell clutch slip from an rpm flare during a shift.
This listing is for the 2015 Nissan 370Z. ACT lists NZ2-HDG6 for the 2009-2020 370Z and 2008-2013 G37 and 2014-2015 Q60 with the VQ37VHR, the 2008 G35 sedan and 09/2006-2009 350Z with the VQ35HR. Earlier 350Z and G35 cars with the VQ35DE take ACT's NZ1 kits instead. Match your old pressure plate and disc spline, or send us year and VIN, especially if the car has had a flywheel or transmission swap.

For a street car with moderate power, the NZ2-HDSS keeps the same Heavy Duty plate with an organic disc and far smoother takeoff. If 574 ft-lb is not enough, the NZ2-XTG6 moves to the Xtreme plate with a heavier pedal.

It can be driven on the street, but ACT describes engagement as aggressive. For a car that mostly sees traffic, the NZ2-HDSS organic kit is smoother.
ACT describes it as light to moderate. Its Heavy Duty plates typically add 15 to 40 percent pedal effort over stock, depending on the application.
ACT lists the N024 pressure plate, 6250306 disc, PB1012 pilot bushing and AT01 alignment tool. No release bearing is listed, so replace it separately if needed.
No. ACT lists NZ2 kits for the VQ35HR 350Z from 09/2006 and VQ37VHR cars. Earlier VQ35DE 350Z and G35 models use the NZ1 kits.
ACT says race discs usually only need a few hard slips to lap in the surfaces before normal driving or racing, and warns against overheating the clutch while doing it.
Both use the Heavy Duty plate and a 6-pad ceramic disc. HDG6 has a spring-center hub that damps driveline vibration; HDR6 is a rigid hub for dedicated race use.
