Clutch Masters 850 Strapped Series Twin Disc Clutch Kit 06-09 Legacy / 04-21 STI | Smooth Engagement | High-Performance Twin Disc Clutch Kit
Overview
The Clutch Masters 850 Strapped Series Twin Disc Clutch Kit is engineered for Subaru Legacy (2006-2009) and WRX STI (2004-2021) models, designed to deliver a balance between street drivability and track-capable performance. This twin disc setup is ideal for enthusiasts seeking a clutch that can handle increased power levels without sacrificing smooth engagement or manageable pedal effort. It’s perfect for daily-driven Subarus with upgraded powertrains or those looking for a more robust clutch solution for spirited driving and occasional track use.
Built with a focus on durability and refined operation, the 850 Strapped kit utilizes drive straps to isolate the pressure plate and mid-plate between the two ceramic discs, virtually eliminating chatter and harsh engagement common in traditional twin disc clutches. The billet aluminum cover is precision machined and hard anodized for superior strength and minimal flex, ensuring consistent clutch actuation and enhanced clamping force. This engineering approach reflects Clutch Masters’ commitment to combining race-proven technology with street-friendly characteristics.
For Subaru owners, this clutch kit means reliable power transfer with confidence-inspiring engagement. The combination of a sprung ceramic disc and a rigid ceramic disc provides excellent holding capacity without slipping, while maintaining a pedal feel that won’t fatigue the driver during daily use. Whether upgrading from a single disc or an older twin disc setup, the 850 Strapped Series offers a significant improvement in drivability and durability tailored to Subaru’s unique drivetrain demands.
