Spec Clutch SH99MT2 Stage D-Trim Twin Disc Clutch Kit

The Spec Clutch SH99MT2 Stage D-Trim Twin Disc Clutch Kit is a high-performance dual-disc clutch system engineered for serious street and track applications. Spec's D-Trim designation refers to the friction material compound used on the clutch disc faces, designed to deliver aggressive, high-torque holding capacity while maintaining drivability under demanding conditions.

Twin disc clutch systems like the SH99MT2 split the clamping load across two friction surfaces, reducing pedal effort compared to single large-diameter performance clutches while dramatically increasing torque capacity. This makes the SH99MT2 an ideal upgrade for highly modified engines producing power levels that exceed the limits of OEM or single-disc performance clutches.

Key Features:

• Twin Disc Design: Dual friction surfaces for increased torque capacity without excessive pedal load
• D-Trim Friction Material: Spec's performance compound optimized for high-heat, high-load environments
• Billet Aluminum Floater Plate: Lightweight intermediate floater for precise disc separation and smooth engagement
• High-Clamp Pressure Plate: Engineered for maximum holding force on performance and race builds
• CNC-Machined Components: Tight tolerances for consistent, repeatable performance
• Street and Track Compatible: Suitable for aggressive street use, road racing, drag racing, and time attack applications

The Spec SH99MT2 kit includes the pressure plate assembly, twin friction discs, and floater plate. As with all Spec twin disc systems, a break-in procedure is recommended to properly seat the friction surfaces and achieve optimal clutch feel and longevity.
