ACT 2015 Nissan 370Z XT/Race Sprung 6 Pad Clutch Kit
ACT NZ2-XTG6 is the strongest single-disc kit ACT makes for the VQ37VHR Nissan 370Z, listed here for the 2015 model. It combines ACT's Xtreme pressure plate with a spring-centered six-pad ceramic disc. Owners usually land on this part after adding a supercharger or turbo kit to a 370Z and finding that the factory clutch, or a milder street upgrade, slips as soon as boost arrives. If the car is naturally aspirated with bolt-ons, this kit is more clutch than you need; see the comparison below.
ACT rates the kit at 695 ft-lb at the crank, 142 percent more than the factory clutch, on a 9.8 in (250 mm) ceramic disc with a 1 in input shaft. The Xtreme plate is where that capacity comes from: ACT's diaphragm design raises clamp load and reduces deflection, at the cost of a heavier pedal. ACT describes the feel as moderate to heavy pedal effort with aggressive engagement, and its general guidance is that Xtreme plates raise pedal effort roughly 50 to 80 percent over stock depending on the car.
The 6250306 disc uses six ceramic pads on a spring-centered hub. The pads tolerate far more heat than an organic facing, which matters on a heavy, powerful car doing launches or track laps, and the springs damp torsional vibration so gear rattle stays close to OE. ACT notes engagement is harsher but shifting is faster than with a full-face street disc.
Kit contents per ACT: N024X Xtreme pressure plate, 6250306 six-pad sprung race disc, PB1012 pilot bushing and AT01 alignment tool. There is no release bearing in this kit, so plan on sourcing the release component for your car separately if it is worn.
Check fluid level and condition and bleed the system first, since air or a tired hydraulic release can feel like a worn clutch. Then do a fourth-gear pull from about 2,500 rpm at full throttle; if engine speed jumps ahead of road speed, the clutch is not holding. Our slipping diagnosis guide lays out the checks, and shift flare vs. slip explains how to tell clutch slip from other drivability faults.
Our listing is titled for the 2015 Nissan 370Z with the VQ37VHR and six-speed manual. ACT's application list for NZ2-XTG6 covers the 2009-2020 Nissan 370Z, the 09/2006-2009 Nissan 350Z with the VQ35HR, the 2008 Infiniti G35 with the VQ35HR, the 2008-2013 Infiniti G37 and the 2014-2015 Infiniti Q60. It does not fit the earlier VQ35DE 350Z, which uses ACT's NZ1 kits. If your car's build date is close to a changeover, or the engine has been swapped, send us the year and VIN before ordering. More clutch and drivetrain parts are in our rebuild kits and clutch section.
For a naturally aspirated 370Z or a daily-driven car with light boost, the NZ2-HDSS Heavy Duty street kit keeps a lighter pedal and organic engagement. The NZ2-HDG6 uses the same six-pad sprung disc with a lighter Heavy Duty plate. Step up to the XTG6 when the power level genuinely needs the Xtreme clamp load.

No. ACT lists NZ2-XTG6 for the VQ35HR 350Z from 09/2006 through 2009 and the VQ37VHR cars. Earlier VQ35DE 350Z and G35 coupes use ACT's NZ1 kits.
No. ACT's kit contents are the N024X pressure plate, 6250306 disc, PB1012 pilot bushing and AT01 alignment tool. Inspect your release components and replace them separately if they are worn.
ACT rates it at 695 ft-lb at the crank, 142 percent over the factory 370Z clutch. That covers most supercharged and turbocharged single-disc builds.
ACT describes it as moderate to heavy. ACT says its Xtreme pressure plates typically increase pedal effort 50 to 80 percent depending on the application.
No flywheel is included. Resurface the stock flywheel or install ACT's 600590 XACT Streetlite, the flywheel ACT pairs with this kit.
The sprung hub keeps gear rattle at OE to mild levels per ACT, but engagement is aggressive and ACT recommends the kit for high horsepower street or race use.
