Action Clutch Chromoly Lightweight Flywheel 2004-2021 STI | Performance Enhancement | Drivetrain Upgrade

Overview

The Action Clutch Chromoly Lightweight Flywheel is a high-performance upgrade designed specifically for Subaru WRX STI models from 2004 to 2021. This flywheel reduces rotational mass, resulting in quicker engine response, sharper throttle feel, and improved acceleration. It’s an ideal choice for enthusiasts looking to enhance their vehicle’s responsiveness, whether for street driving, spirited canyon runs, or competitive racing. Crafted from premium Chromoly steel, this flywheel offers a perfect balance of strength, durability, and weight savings, making it a reliable upgrade that can handle the demands of high-revving turbocharged engines.

Built with a focus on engineering excellence, the Action Clutch flywheel undergoes specialized heat treatment to withstand extreme thermal loads and high RPMs, tested up to 18,000 RPM. Its resurfacable surface extends the lifespan of the component, providing excellent value for long-term use. While the reduced mass improves throttle response and acceleration, it may introduce increased noise, vibration, and harshness (NVH), a common trade-off in lightweight flywheel designs. Subaru owners who seek a more engaging driving experience will appreciate the direct feel and improved drivetrain durability this product offers. As a community-focused brand, Subimods is proud to offer parts that are tailored specifically for Subaru enthusiasts, ensuring perfect fitment and performance gains.
