ECS Tuning Performance Clutch Kit & Single-Mass Flywheel Conversion

Take your driving dynamics to the next level with our S54 Performance Clutch Kit and Lightweight Flywheel. Designed for enthusiasts who demand more from their vehicles, this upgraded kit offers improved performance, durability, and a superior driving experience.

S54 Performance Clutch Kit

From the factory, the E46 M3 featured a dual-mass flywheel and a self-adjusting clutch for comfort and ease of use. While suitable for daily driving, it falls short when it comes to durability and power handling. The ECS S54 Performance Clutch Kit delivers where the factory setup can't:

• Increased Power-Holding Capacity: A proprietary, full-face sprung clutch disc paired with a heavy-duty pressure plate ensures reliable performance under demanding conditions.
• Enhanced Pedal Feel: Experience precise engagement for better control and feedback during spirited driving.
• Complete Kit: Includes a performance pressure plate, clutch disc, throwout bearing, pilot bearing, alignment tool, pressure plate screws, and flywheel bolts.

Performance Lightweight Flywheel

The stock 24.2-lb. dual-mass flywheel prioritizes vibration damping and smooth shifting over performance. Our lightweight flywheel weighs just 16.5 lbs. and is built for enthusiasts seeking improved throttle response and drivability:

• Hardened 4140 Chromoly Steel: Ensures exceptional durability, wear resistance, and engagement feel.
• Zinc-plated for Corrosion Resistance: Protects the flywheel in all conditions, on and off the track.
• Performance-Oriented Design: Allows quicker RPM changes, smoother “heel-toe” downshifts, and enhanced acceleration.
• SFI Tested and Certified: Proven to withstand the rigors of motorsport and street use with unmatched reliability and safety.

Why SFI Certification Matters

SFI certification guarantees the flywheel meets industry standards for competitive motorsports. Each ECS flywheel is individually tested and assigned an SFI serial number to ensure it’s safe for high-stress racing conditions and reliable for long-term street use.

Single Mass Flywheel Conversion:

Audible chatter from the transmission after installation is considered normal. As with most single mass flywheels, there is less dampening in the flywheel to reduce "gear noise." This chatter noise may be more present when the transmission fluid temperatures are hotter and may be intensified by other modifications. Most gearboxes will experience some chatter noise at hotter temperatures. Please be advised that this noise will disappear once the clutch pedal is depressed. This symptom may be lessened by adjusting transmission fluid weight, turning off electrical/driveline consumers (A/C, High Beams, ETC.), and by raising the RPM slightly.
