ACT Performance Street Sprung Clutch Disc 2004-2021 STI

DESCRIPTION

The ACT Performance Street Sprung Clutch Disc is designed for 2004–2021 Subaru STI models and is ACT’s most popular performance replacement disc. Built with premium organic friction materials featuring high copper content, this disc delivers improved heat transfer, smooth engagement, and quicker shifting compared to stock. A reduced marcel design sharpens shift response while maintaining daily drivability. The spring-centered hub uses bushings and cone springs similar to factory clutch discs, providing frictional dampening that reduces noise, improves clutch life, and enhances overall reliability.

WHY?

This disc is ideal if you want a noticeable performance upgrade without sacrificing street manners. It offers a smooth, predictable feel with improved durability over OEM-style discs, making it a great choice for spirited street driving and light race use where longevity, comfort, and consistent engagement still matter.
