Z1 Motorsports Z32 Non Turbo 4140 Forged Steel Ultra Light Weight Flywheel

The Z1 Ultralight NA flywheel is precision machined to reduce rotating weight while maintaining strength.


  • 9.30 lbs
  • Allows engine to more rapidly transfer power to the drive train and to have quicker throttle response.
  • Motor will rev faster under acceleration 
  • Meets SFI spec 1.1 or 1.2
Less mass on the ouside rim is a big factor in reducing the rotational inertia of this flywheel. 
The distance the mass is located from the center of rotation is very important to the value of the moment of intertia.

This flywheel has the lowest moment of inertia available of any aftermarket  production Z32 NA flywheel.  Which translates to a faster revving motor.

The Z1 Lightweight non-turbo flywheel is designed to work with a stock clutch and is compatible with most aftermarket clutches with a stock diameter disc.
