Key Features & Benefits

• Twin Disc Design — Doubles the friction surface area compared to a single disc setup, enabling significantly higher torque capacity without increasing pedal effort beyond street-usable levels.
• SS-Trim Pressure Plate — SPEC's SS-Trim cover assembly provides increased clamp load over the stock unit while maintaining consistent release characteristics for predictable engagement.
• Organic Disc Option (O-Trim) — The organic friction material delivers smoother, more progressive clutch engagement compared to metallic alternatives, making this kit an ideal choice for high-power street and street/strip applications.
• Precision-Machined Components — SPEC manufactures each component to tight tolerances, ensuring proper balance, reduced vibration, and long service life under demanding conditions.
• Direct OEM-Style Fitment — Engineered specifically for the R32/R33 Skyline drivetrain, this kit installs using factory bolt patterns and interfaces, minimizing modification requirements.
• High Torque Capacity — The twin disc configuration is capable of handling the elevated torque output of modified RB20DET and RB26DETT engines, including turbo-upgraded applications.
• Durable Construction — Built to withstand repeated heat cycles from spirited driving, road course use, and drag strip launches while maintaining consistent clamp load.
