Spec 2013-2016 Ford Focus ST EcoBoost Aluminum Flywheel

Specifications   Part Details: SPEC tuned billet flywheels are engineered with vehicle-specific rotating mass targets based on how each platform responds under different driving conditions. Rather than using a one-size-fits-all lightweight design, each flywheel is tuned to balance throttle response, drivability, and clutch engagement for the intended application. Manufactured from high-quality steel and aluminum alloys, these flywheels are precision machined to tight tolerances to ensure a flat clutch mating surface and consistent rotational balance. This results in smooth engagement, predictable drivability, and reduced stress on clutch components over time. SPEC billet flywheels are suitable for a wide range of uses, from daily-driven street vehicles to high-performance and motorsport applications, where reliable power transfer and long-term durability are critical. Key Features Vehicle-specific tuned rotating mass for balanced drivability and performance Billet steel and aluminum construction for strength and durability Precision machined to .001 in. tolerances for flat clutch engagement Optimized balance for smooth rotational characteristics Supports consistent clutch engagement and extended clutch life Suitable for street, performance, and racing applications What’s Included SPEC tuned billet flywheel Properly machined clutch friction surface Application-specific design for correct fitment Frequently Asked Questions (FAQ) Is this flywheel suitable for daily driving? Yes. SPEC tunes rotating mass based on vehicle behavior, allowing these flywheels to maintain street-friendly drivability while improving throttle response. Will a lightweight flywheel cause chatter or drivability issues? Some increase in drivetrain feedback is normal when reducing rotating mass, but the tuned design helps minimize harshness compared to generic lightweight flywheels. Does this flywheel improve performance? Reduced rotational mass can improve engine response and rev matching, particularly during acceleration and shifting, while maintaining stable clutch engagement. Is break-in required? Flywheel break-in follows the clutch manufacturer’s recommendations. Proper clutch break-in is important to ensure optimal engagement and surface mating. Can this flywheel be used with performance clutch kits? Yes. SPEC billet flywheels are designed to pair correctly with compatible OEM and aftermarket clutch kits for reliable torque transfer. Related Drivetrain Components Clutch Kits – often paired with flywheels to ensure proper fitment, engagement, and torque capacity. Transmission Mounts – help limit drivetrain movement, which can affect clutch engagement and flywheel performance under load. Shifters – can benefit from reduced rotational mass when combined with lightweight flywheels. Shifter Bushings – improve shift precision and complement drivetrain upgrades involving flywheel changes.
