The SPEC Clutch SA863FS-A4 is a high-performance Stage 3+ clutch kit engineered specifically for 1996-2005 Audi A4 1.8T models equipped with the larger S4 clutch conversion setup. This flagship stage clutch is designed for high-powered street and race applications that require exceptional torque capacity with manageable, street-friendly engagement characteristics.

Key Features:

• Carbon semi-metallic full-faced friction disc offers superior heat tolerance and durability
• High-clamp pressure plate with CNC-machined castings and induction-hardened diaphragm
• Double-sprung high-torque hub with heat-treated components for strength and flexibility
• Conservatively rated to handle up to 671 ft-lbs of torque at the flywheel
• Non-SAC (Self-Adjusting Clutch) design for increased clamp load and RPM capability
• Includes pressure plate, friction disc, bearing, and alignment tool

Important Installation Requirements: This clutch kit must be used with a SPEC steel flywheel (SA01SB or SA01AB) for proper fitment and performance. The conversion allows A4 1.8T models to utilize the larger 240mm S4 clutch diameter versus the stock 228mm setup. Hand-built in the USA by SPEC Clutch, Inc., this kit is ideal for modified vehicles with bolt-on upgrades including intakes, exhausts, and turbo enhancements. Perfect for street driving, autocross, drag racing, road racing, rally, and drift applications.
