This ACT heavy - duty clutch kit, model NZ1 - HDR6, is specifically designed for 2003 - 2006 Nissan 350z and 2006 Infiniti G35 cars. It features a rigid 6 - pad race clutch disc and a popular heavy - duty pressure plate. You'll enjoy light to moderate pedal effort with an aggressive engagement and it can handle up to 580 ft/lbs of torque. This kit is perfect for racing only. The ACT heavy - duty pressure plates use an exclusive diaphragm design. It increases clamp load, reduces deflection, and maximizes clutch life. The diaphragms go through a four - stage heat - treating process for top - notch performance. The pressure plates have precision cover stampings for rigidity and consistency. The 6 - pad rigid race discs are made of high - quality ceramic friction materials. The chrome - moly hub is heat - treated for strength and durability. Its lightweight and rigid design allows for quicker shifts and smooth service. The 6 - pad disc has a harsher engagement but faster shifting, and is great for larger clutch sizes to absorb heat. Key features include light to moderate pedal effort, aggressive engagement with increased gear rattle, recommended for race use only, a torque capacity of 580 ft/lbs, and it's 100% clamp load tested and dynamically computer - balanced for smooth high RPM reliability. What's in the box: a 6 - pad rigid race disc, a heavy - duty pressure plate, an alignment tool, a pilot bushing, and a release bearing.
Using this ACT clutch kit is straightforward. First, make sure your car is a 2003 - 2006 Nissan 350z or 2003 - 2006 Infiniti G35. When installing, use the alignment tool to ensure proper alignment of the clutch disc. The pilot bushing and release bearing should be installed as per the vehicle's standard installation process. Remember, this kit is designed for race use only, so don't use it for regular daily driving. When shifting gears, you'll notice that the engagement is a bit harsh but the shifting is fast. Be prepared for increased gear rattle. As for maintenance, keep an eye on the clutch performance. If you feel a change in pedal effort or shifting smoothness, it might be time to check the clutch components. The pressure plates and discs are built to last, but due to the high - performance nature of the kit, regular inspections during race seasons are recommended. If you're unsure about any part of the installation, use, or maintenance, it's best to consult a professional mechanic.
