LIGHTENED FLYWHEELS (EXCHANGE)

Due to the long stroke characteristics of the 100 engine the flywheel can be lightened substantially with no noticeable loss of torque or detriment to smooth running.

This makes the engine more willing to rev quicker and higher with an all round improvement in performance on a standard or fast road car.

Supplied to suit original 2 or 3 dowel clutch.
