Our latest redesign of our flywheel! It is a lightweight one piece design with no areas that can prematurely fail. Weighing at a little over 12lbs these flywheels will also free up power and allow for quicker engine revs over the factory flywheel. No need to look up those factory torque specs! They are conveniently part of the flywheel! Made for the 300ZX TT. This can be used on an NA with the appropriate bell housing modifications to the NA manual transmission, TT clutch, and starter shim. Flywheels come balanced.
