Lightweight Flywheel for 135, 335 and 535!

Dinan has carefully lightened the stock dual-mass flywheel in order to reduce the amount of energy required to turn it, improving driveline efficiency for faster acceleration and more immediate throttle response.  The Dinan flywheel has been lightened for a substantial 23% reduction in rotational inertia. The improved performance does not come at the expense of the smooth engagement and quiet operation provided by the stock configuration.
