The ACT Streetlite Flywheel (Part Number 600235) is a precision-engineered performance upgrade designed for Subaru Impreza, Legacy, and WRX STI models from 2007 through 2015. Constructed from heat-treated forged material, it delivers superior durability and reduced rotational mass compared to stock flywheels. This optimized design improves throttle response, acceleration, and clutch engagement while maintaining the strength needed for both daily driving and competitive drag applications.
With its one-piece construction, the Streetlite Flywheel minimizes weak points and ensures even heat transfer from the clutch disc, preventing issues like warped inserts or loose ring gears. The induction-hardened ring gear enhances lifespan, while CNC machining and dynamic balancing guarantee smooth and reliable operation at high RPMs. The result is a flywheel that combines precision, strength, and responsiveness for consistent performance under demanding conditions.
Fully serviceable and resurfaceable, the ACT Streetlite Flywheel provides long-term value and simplified maintenance. Whether you’re seeking sharper throttle response for spirited driving or a dependable upgrade for high-stress conditions, this flywheel delivers proven performance and reliability for Subaru enthusiasts.
