The SPEC SS-Trim Super Twin Clutch Kit (SN23SST) is an elite dual-disc performance clutch system engineered specifically for the Nissan Skyline R31, R32, and R33 — covering model years 1985 through 1998. Designed for high-output builds and demanding motorsport applications, this kit delivers exceptional torque capacity and pedal modulation where OEM and single-disc units fall short. Whether you're building a track-focused GT-R or a high-horsepower street machine, the SPEC SS-Trim Super Twin is engineered to handle the power and abuse your Skyline demands.

Key Features & Benefits

• Super Twin Dual-Disc Design — Doubles the friction surface area compared to a single-disc clutch, dramatically increasing torque capacity without requiring excessive clamping force that fatigues the drivetrain.
• SS-Trim Friction Material — SPEC's proprietary SS-Trim compound offers an aggressive, high-grip engagement ideal for performance and motorsport use, providing consistent clamping force under sustained heat cycles.
• High Torque Capacity — Purpose-built to handle heavily modified and turbocharged Skyline engines, making it ideal for builds that have exceeded the limits of OEM or entry-level aftermarket clutches.
• Precision-Machined Components — CNC-machined steel floater and pressure plate components ensure consistent disc spacing, true balance, and long service life even under racing conditions.
• Improved Pedal Feel — Despite its dual-disc configuration, the SPEC Super Twin is engineered to maintain streetable pedal effort, reducing driver fatigue compared to many competing twin-disc systems.
• Direct OEM Replacement Fitment — Engineered as a direct bolt-in replacement for the factory clutch assembly on compatible Skyline platforms — no custom fabrication required.
• Race-Proven Performance — SPEC clutches are trusted by professional motorsport teams and serious enthusiasts worldwide across drag racing, circuit racing, and time attack disciplines.

What's Included

• SPEC SS-Trim Dual-Disc Pressure Plate Assembly
• Two (2) SS-Trim Friction Discs

Specifications

Fitment & Compatibility

The SPEC SN23SST SS-Trim Super Twin Clutch Kit is compatible with the following Nissan Skyline applications:

• 1985–1989 Nissan Skyline R31
• 1989–1994 Nissan Skyline R32 (including GT-R, GTS-T, and GTS variants)
• 1993–1998 Nissan Skyline R33 (including GT-R and GTS25-T variants)

Always verify your specific transmission type and engine configuration before installation. If you are unsure of compatibility with your exact build, consult SPEC's fitment guide or contact a qualified drivetrain specialist.

Installation

The SPEC SS-Trim Super Twin Clutch Kit is designed as a direct bolt-in replacement for the factory clutch assembly on compatible Nissan Skyline platforms. However, due to the precision tolerances required for a dual-disc clutch system and the complexity of Skyline drivetrain configurations — particularly on AWD GT-R models — professional installation by an experienced transmission or drivetrain specialist is strongly recommended. Proper flywheel resurfacing or replacement, throwout bearing inspection, and clutch pedal adjustment should be performed at time of installation to ensure optimal performance and longevity.

Is this clutch street-drivable? Yes — the SPEC SS-Trim Super Twin is engineered with streetability in mind, offering more progressive engagement than many full-race twin-disc alternatives, while still supporting the power demands of highly modified Skyline builds.
