You can enhance the quick-revving performance of the new 4-cylinder turbocharged EcoBoost Mustang with a new lightweight aluminum flywheel from Fidanza. Compatible with the stock clutch, or any aftermarket clutch that works with a factory flywheel, the new Fidanza unit is just 14 pounds compared to the stocker’s 33. Less weight means less wait – your EcoBoost will put more power to the pavement thanks to the lower inertia with a Fidanza flywheel.
