ACT 2015 Nissan 370Z XT/Race Rigid 6 Pad Clutch Kit
ACT NZ2-XTR6 is the race-only end of ACT's single-disc lineup for the VQ37VHR Nissan 370Z, listed here for the 2015 car. It pairs the Xtreme pressure plate with a rigid (unsprung) six-pad ceramic disc. Buyers looking at this kit usually have a boosted or heavily built 370Z that sees drag strip passes or road course sessions, and they have already found that an organic street disc fades or slips once the car is pushed hard. It is not a daily-driver part, and ACT says so plainly.
ACT rates this combination at 695 ft-lb at the crank, 142 percent more than the factory clutch, on a 250 mm (9.8 in) ceramic disc that fits the 1 in input shaft. Capacity comes from the Xtreme diaphragm, which ACT heat-treats in four stages to raise clamp load and cut deflection. The tradeoff is pedal weight: ACT's own guidance is roughly 50 to 80 percent more effort than stock for Xtreme plates, and it describes this kit as moderate to heavy pedal with aggressive engagement.
The disc is what separates XTR6 from the sprung XTG6. Its six ceramic pads ride on a heat-treated chromoly hub with no damper springs. That makes the disc lighter, so the input shaft slows faster and gearchanges are quicker, and the pads shrug off heat that would glaze an organic facing. Without springs, though, crankshaft pulses go straight into the gearbox. ACT warns of increased gear rattle and notes that a rigid hub may increase spline wear, and it recommends this kit for race use only.
In the box, per ACT: N024X Xtreme pressure plate, 6250006 six-pad rigid race disc, PB1012 pilot bushing and AT01 alignment tool. A release bearing is not part of the kit. ACT lists the kit at 16.5 lb.
Rule out the hydraulics first. Old fluid, air in the line or a weak release can feel like a clutch that will not hold or will not release. Then do a load test: fourth gear from about 2,500 rpm at wide open throttle, watching whether rpm rises faster than road speed. Our slipping diagnosis guide covers that test, and flare versus slip helps if you are unsure what you are feeling. If the car is mostly street driven, the sprung NZ2-XTG6 or the full-face NZ2-XTSS will be far easier to live with.
Our listing is for the 2015 Nissan 370Z with the 3.7L VQ37VHR and six-speed manual. ACT's application list for NZ2-XTR6 is wider: the 2009 to 2020 370Z, 2008 to 2013 Infiniti G37, 2014 to 2015 Q60, the 2008 G35 sedan and the late 2006 to 2009 350Z with the VQ35HR. Earlier VQ35DE 350Zs use a different kit. Trim levels, Nismo cars included, share this part per ACT. If your car is a different year or has had a transmission swap, send us the year and VIN before ordering. More clutch hardware is in our rebuild kits category.

ACT recommends it for race use only. The rigid six-pad disc gives harsh engagement and more gear rattle, and the Xtreme plate adds a heavier pedal.
Both use the N024X Xtreme plate and are rated 695 ft-lb. XTR6 has a rigid hub with no damper springs, which is lighter and shifts faster; XTG6 has a sprung hub that softens takeoff and reduces gear rattle.
No. ACT lists the contents as the N024X pressure plate, 6250006 disc, PB1012 pilot bushing and AT01 alignment tool.
ACT lists the same kit for 2009 to 2020 370Z and 2008 to 2013 G37 with the manual gearbox. Our listing is for the 2015 car, so send the year and VIN and we will confirm.
ACT says race discs usually need only a few hard slips to lap in the surfaces. Do not overheat the clutch while doing it.
