Product Description

The ACT 600480 Streetlite Flywheel is a direct-fit lightweight performance flywheel engineered to improve engine responsiveness and throttle feel in a range of popular manual-transmission performance cars from Subaru, BRZ, FR-S, and Toyota 86 platforms. By significantly reducing rotational mass compared to stock units, this forged chromoly Streetlite design offers quicker rev-ups, sharper clutch engagement, and improved acceleration response - making it an excellent upgrade for daily driven performance cars, weekend track use, and spirited street applications.

Constructed with a one-piece forged chromoly body and induction-hardened ring gear, the ACT Streetlite Flywheel balances durability with lightweight performance. It includes necessary installation hardware and a pilot bearing, and is dynamically balanced to minimize vibration at higher RPMs. This flywheel maintains compatibility with stock and many aftermarket clutch systems while providing noticeable improvements in drivability and feel. Fitment covers many Subaru WRX years and other popular 2.0L platforms; however, confirm compatibility on 2018+ WRX 240 mm clutch conversions before purchase.
