XACT Streetlite Design:

The XACT Streetlite represents ACT's lightweight flywheel line designed for street and race applications. The Streetlite designation indicates the flywheel is lighter than the factory unit, providing improved throttle response and acceleration while maintaining drivability for street use. The weight reduction is optimized to provide maximum performance benefit without compromising low-RPM drivability or causing excessive gear rattle.

Heat-Treated Forged Construction:

The flywheel is manufactured from heat-treated forged steel, providing exceptional strength and toughness. The forging process creates a denser grain structure compared to cast flywheels, resulting in superior strength and resistance to warping under high temperatures. The heat treatment further increases hardness and durability, ensuring the flywheel maintains its shape and friction surface even under demanding race conditions.

One-Piece Construction:

The one-piece design eliminates the failure points associated with multi-piece flywheels. There are no inserts to warp or ring gears to come loose - the entire flywheel is machined from a single forging. This construction provides maximum reliability and uniform, efficient heat transfer from the clutch disc. The one-piece design is essential for high-performance applications where reliability is critical.

Induction-Hardened Ring Gear:

The ring gear is induction-hardened to provide maximum life and resistance to wear. The hardening process increases the surface hardness of the gear teeth, preventing premature wear from starter engagement. This ensures the flywheel will provide reliable starting performance for the life of the vehicle, even with frequent starts in racing applications.

CNC-Machined and Computer-Balanced:

The flywheel is CNC-machined to precise tolerances and dynamically computer-balanced for smooth high-RPM reliability. The precision machining ensures a perfectly flat friction surface for optimal clutch disc contact. The computer balancing eliminates vibration, ensuring smooth operation from idle to redline. This precision manufacturing is what separates ACT from budget alternatives.

Improved Engine Response and Acceleration:

The reduced flywheel weight provides noticeably improved engine response and acceleration. With less rotational mass to overcome, the engine revs more freely and responds more quickly to throttle input. The improvement is measurable on the dyno and immediately noticeable on the street and track. The faster rev response makes heel-toe downshifting and rev matching significantly easier.

Mild Gear Rattle:

Lightweight flywheels may produce mild gear rattle at idle, which is normal and not a cause for concern. The rattle occurs because the reduced flywheel mass doesn't dampen drivetrain vibrations as effectively as the heavy factory flywheel. The rattle disappears once the clutch is engaged or the engine is above idle. This is a characteristic of lightweight flywheels and is accepted by enthusiasts as a trade-off for improved performance.
