The stock flywheel has been relieved of 7 lbs. for an 18% reduction in weight and a 40% reduction in rotational inertia. SMG equipped cars receive the added benefit of a reduction in shifting time, which results in smoother gear changes in both the manual and ''automatic'' modes. The lightened flywheel maintains the smooth engagement and quiet operation provided by the stock configuration.
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.
