Spec 2013-2016 Ford Focus 2.0T ST EcoBoost Aluminum Flywheel

Part Details:

SPEC tuned billet flywheels are engineered based on how specific vehicles respond to changes in rotating mass across different driving environments. Rather than using a generic lightweight design, each flywheel is developed to balance throttle response, drivability, and engagement characteristics for the intended application.

While optimized for particular platforms, these flywheels can support a wide range of driving styles, from daily street use to high-performance and racing applications. The tuned approach helps avoid common drawbacks associated with overly aggressive lightweight flywheels, such as unstable engagement or inconsistent drivability.

All SPEC tuned billet flywheels are manufactured using high-quality steel and aluminum materials and are precision machined to industry-leading .001 inch tolerances. This ensures a flat clutch mating surface, smooth rotational balance, and consistent performance, contributing to improved drivability and extended clutch life.

Frequently Asked Questions (FAQ)

Is this flywheel suitable for daily driving?
Yes. The tuned rotating mass design allows these flywheels to maintain predictable engagement and drivability for street-driven vehicles.

How does this differ from a generic lightweight flywheel?
Unlike one-size-fits-all designs, SPEC tuned billet flywheels are developed based on vehicle behavior, helping balance responsiveness with drivability.

Will this flywheel increase drivetrain noise or vibration?
Some change in feedback is normal when reducing rotating mass, but the tuned design helps minimize excessive noise or harshness compared to aggressive lightweight options.

Does this flywheel require break-in?
Flywheel break-in follows the clutch manufacturer’s recommendations. Proper clutch break-in is important for optimal surface mating and longevity.

Can this flywheel be used with aftermarket clutch kits?
Yes. SPEC billet flywheels are designed to work with compatible OEM and performance clutch kits for reliable engagement and torque transfer.
