B58 Twin Disc Clutch Kit for BMW M140i / M240i / 340i / 440iMany reinforced clutch systems are difficult to drive in daily use due to heavy pedal force, noisy operation or aggressive engagement. This twin disc clutch system combines high torque reserves with a near-OEM pedal feel, smooth operation and controlled engagement behaviour.Advantages of the PTB Twin Disc Clutch Kit:Near-OEM pedal feel without increased pedal forceNo clutch pedal stop requiredSmooth and precise engagementSignificantly increased torque capacityLarger friction surface for improved thermal stabilityReduced wear due to optimized load distributionTangential spring mounted intermediate disc for smoother operationFinely balanced componentsSuitable for daily driving and high-performance applicationsDue to the increased friction surface, the transmitted load is distributed more evenly and thermal stress is reduced. This makes the clutch kit ideal for Stage 2 and Stage 3 performance builds while maintaining excellent drivability.Clutch configuration:Flywheel: Single-mass flywheelFriction material: Sinter-metal / organicTorsion damper: DampedPressure plate: StandardQuality & Manufacturing:All components are manufactured in-house or sourced from well-known OEM suppliers. High-strength 12.9 grade bolts are included in the scope of delivery. The complete system is Made in Germany.Important note regarding the single-mass flywheel:Due to the solid single-mass flywheel, transmission and engine noises may occur. This is technically inherent and typical for performance clutch systems.Suitable for the following BMW models with B58 engine:BMW M140i F20 / F21BMW M240i F22 / F23BMW 340i F30 / F31BMW 440i F32 / F33 / F36Engine:B58B30A Kit contains: Steel single-mass flywheel Pre-assembled intermediate disc Friction disc module depending on selected configuration 6x pressure plate bolts 8x flywheel bolts Release bearing including lever
