Cosworth smaller 9 bolt flywheel to suit Pinto 8 ½” clutch
Smaller 9 bolt flywheel to suit Pinto 8 1/2″ clutch. This will fit inside our bellhousings and will accept any Ford 8 1/2″ clutch.
By reducing the weight of the flywheel over the standard Cosworth YB item to as little as a half, the resulting reduced inertia gives better acceleration, especially in the lower gears. In addition, the reduced weight at the flywheel edges allows quicker gear changes, and increased engine braking. Comes with integral starter ring (ring gear is machined into the flywheel).
For use with any Ford Pinto 8 1/2″ clutch.
