XACT Streetlite Flywheel Subaru

The XACT Streetlite Flywheel Subaru is purpose-built for high-performance Subaru applications where weight reduction and reliability are non-negotiable. This 124-tooth flywheel is engineered for STI and Legacy models from 2002–2013, delivering the rotational efficiency demanded by tuners, street enthusiasts, and weekend track drivers. Whether you're upgrading a stock 2.0L or 2.5L engine or maximizing the potential of a modified platform, the XACT Streetlite addresses the critical need to reduce rotating mass without compromising durability or clutch compatibility.

Constructed from chromoly steel, this internally balanced flywheel sheds unnecessary weight while maintaining structural integrity under demanding conditions. At 15.5 pounds, it cuts rotational inertia compared to factory units, enabling faster throttle response, quicker acceleration, and sharper engine braking—all critical advantages in both street driving and competition. The internal balance design ensures smooth operation without external counterweights, and SFI 1.1 certification guarantees it meets sanctioning body standards for drag racing and road course events. The 124-tooth ring gear maintains full compatibility with OEM and aftermarket clutch systems, ensuring seamless integration into your existing drivetrain.

Subaru enthusiasts leveraging forced induction, turbo upgrades, or comprehensive engine builds will benefit most from this lightweight alternative. The reduced rotational mass pairs exceptionally well with performance clutches and upgraded transmissions, improving shift quality and power delivery while reducing parasitic losses in the drivetrain. Installation requires disconnection of the transmission and clutch assembly, making it suitable for experienced DIY builders or professional shops. Verify fitment with your specific model year and engine displacement—this unit is engineered exclusively for 2002–2013 STI and Legacy 2.0L and 2.5L platforms.
