2-Disc Clutch Kit for BMW G80 / G81 / G82 / G83 M3 & M4

The 2-Disc Clutch Kit was developed for high-performance BMW M3 and M4 models with the S58 engine and combines high torque capacity with excellent everyday drivability. Designed and manufactured in Germany, the complete system is engineered for precise operation, high thermal stability and reliable power transmission – from performance-oriented street vehicles to heavily modified builds.

Unlike many high-performance clutch systems, the 2-Disc Clutch Kit maintains a pedal feel close to the OEM setup without requiring significantly increased clutch pedal pressure. The system is designed to handle up to 1100 Nm / 808 ft-lb while remaining suitable for daily use.

A major advantage of the system is its configurable design. The flywheel and friction disc combination can be selected according to the vehicle setup, power level and intended use.

Configuration Options:

Flywheel:

• CNC DMF – Dual-Mass Flywheel: Designed for increased comfort and reduced drivetrain noise while maintaining high torque capacity.
• CNC SMF – Single-Mass Flywheel: Reduced rotating mass and more direct power transmission for performance-focused applications.

Friction Disc Configuration:

• Organic / Organic: Maximum everyday drivability with smooth engagement and excellent comfort.
• Sinter / Organic: Increased torque capacity with a balance between performance and street usability.
• Sinter / Sinter: Maximum performance and torque capacity for highly modified and motorsport-oriented vehicles.

Product Advantages:

• Torque capacity up to 1100 Nm / 808 ft-lb
• 2-disc clutch system for increased friction surface
• Configurable CNC-machined DMF or SMF flywheel
• Choice of Organic / Organic, Sinter / Organic or Sinter / Sinter friction discs
• No significantly increased clutch pedal pressure
• No additional pedal stop required
• Pedal travel remains close to the OEM configuration
• 100% suitable for everyday use depending on selected configuration
• Increased friction surface for improved thermal capacity
• Improved heat dissipation under high loads
• Reduced clutch disc wear
• Precision-balanced components for smooth operation
• Tangential spring-mounted intermediate disc for improved comfort and reduced noise
• High-strength 12.9-grade hardware for flywheel and pressure plate
• Developed and manufactured in Germany

The twin-disc design significantly increases the available friction surface compared to a conventional single-disc clutch. This allows the system to transmit considerably higher torque while simultaneously distributing thermal load across a larger surface area. The result is improved thermal stability and reduced wear under demanding operating conditions.

The intermediate disc is tangentially spring-mounted to improve engagement characteristics and reduce unwanted noise. All rotating components are precisely balanced to ensure smooth operation even at high engine speeds.

Flywheel Selection:

The clutch kit can be configured with either a CNC-machined dual-mass flywheel (DMF) or a CNC-machined single-mass flywheel (SMF).

• DMF: Recommended for customers who prioritize everyday comfort, smoother drivetrain behavior and reduced transmission noise.
• SMF: Recommended for performance-oriented applications where direct response and reduced rotating mass are the priority.

Please note: When selecting the solid single-mass flywheel configuration, transmission and engine noises may become more noticeable compared to the OEM dual-mass flywheel. This is a normal characteristic of a performance-oriented single-mass flywheel system.

Friction Disc Selection:

• Organic / Organic: Ideal for street vehicles and performance builds where comfort and smooth engagement remain a priority.
• Sinter / Organic: Suitable for higher-power applications requiring increased friction capability while maintaining reasonable everyday drivability.
• Sinter / Sinter: Designed for maximum torque transmission and demanding performance or motorsport applications. Engagement is noticeably more aggressive compared to organic configurations.

The friction disc modules are supplied pre-assembled in the correct configuration, eliminating the need to determine the installation order of the individual discs.

Suitable for the following vehicles:

• BMW M3 G80
• BMW M3 Touring G81
• BMW M4 G82
• BMW M4 Cabriolet G83

Scope of Delivery:

• 1x selected CNC flywheel – DMF or SMF
• 1x pre-assembled intermediate disc
• 1x configured 2-disc friction module
• 6x pressure plate screws
• 8x flywheel screws
• 1x release bearing
• 1x release lever
• Required high-strength mounting hardware

The 2-Disc Clutch Kit provides a configurable high-performance solution for BMW G8X M3 and M4 vehicles. With multiple flywheel and friction material options, the system can be individually matched to the required balance of everyday comfort, torque capacity and performance.
