Spec 07-08 350Z/07+ G35 Stage 4 clutch kit (p/n SN35-2BS Required)

This SPEC Stage 4 clutch kit is built with a sprung, multi-plate design, offering a significant increase in torque capacity over stock. The sprung hub helps absorb shock and vibration, making it a more manageable option for daily driving compared to unsprung designs, while still handling serious power. It's a well-built setup for drivers looking to push their 2007-2009 Nissan 350Z, 2007-2008 Infiniti G35, 2008-2013 Infiniti G37, or 2009-2014 Nissan 370Z well beyond factory limits.

The Stage 4 designation means this clutch is engineered for high-horsepower applications, often paired with significant engine modifications. It features a high-performance friction material designed for aggressive engagement and maximum heat dissipation, crucial for preventing fade during spirited driving or track use. While it offers a substantial grip, the sprung design aims to provide a more comfortable pedal feel than many other high-performance clutch options, though it will be firmer than the original clutch. Keep in mind that a clutch upgrade of this caliber often requires a compatible flywheel, and SPEC specifies the SN35-2BS as a required component for this kit.

Installing a Stage 4 clutch is a substantial undertaking, typically requiring the removal of the transmission. It's recommended to have a professional mechanic perform this service if you're not experienced with drivetrain work. This kit is a solid choice for those who have heavily modified their vehicle and need a clutch that can reliably transfer that increased power to the wheels without slipping.
