This ACT XACT Streetlite Flywheel for the 2003-2006 Nissan 350Z and Infiniti G35 is lighter than stock which means that there will be less rotational mass which creates a faster engine response, along with a bump in more horsepower and more torque.
The flywheel has been forged, as well as CNC machined along with being dynamically computer balanced, and is a one-piece construction which allows for less opportunity for failure and provides uniform efficient heat transfer from the clutch disc. Additionally, it has gone through a heat-treated forging process which provides more strength with induction-hardened ring gears for maximum life.
Flywheel tooth count: 124
Flywheel weight: 17.1 lbs
