This 8.5-inch triple-disc racing clutch is designed for the BMW B58 engine to provide excellent performance and reliability, especially suitable for high-performance racing and competitive environments.

Product Description:
Applicable Models/Engine: Suitable for racing cars, modified cars and high-performance models equipped with BMW B58 engines.
Size: 8.5 inches, compact design, optimized clutch response speed and pedal feel.
Disc Type: Triple Disc design (Triple Disc), providing higher torque carrying capacity, suitable for high-power output racing engines, and can better withstand extreme loads on the track.
Material:
Clutch Plate: Made of high-strength chromium-molybdenum steel (Chromoly Steel), it has excellent tensile strength, wear resistance and fatigue resistance, ensuring long-term stability under extreme working conditions.
Flywheel: Equipped with a lightweight flywheel, it can reduce engine inertia, improve shift response speed and acceleration performance, and is particularly suitable for racing environments that require fast shifting.
Number of spline keys: 14-tooth spline key design ensures high-precision transmission engagement, enhances the synchronization between the clutch and the flywheel, and improves power transmission efficiency and reliability.
Performance characteristics:
The three-disc design provides a larger engagement surface, enhances the clutch's grip and durability, and is particularly suitable for high-torque and high-speed environments.
The lightweight flywheel design significantly reduces inertia, optimizes engine response, and improves acceleration performance.
The chrome-molybdenum steel material ensures the clutch's high strength, high temperature resistance, and wear resistance, making it suitable for use in harsh track environments.
The 14-tooth spline key design improves engagement accuracy, reduces clutch operation hysteresis and friction loss, and provides a smoother and more precise control experience.
Applicable scenarios:
Racing use: Especially suitable for modified racing cars, track cars, and high-performance engine modification applications, it can withstand extreme working conditions and meet high-performance requirements such as frequent shifting and high-torque output.
Competitive sports: Suitable for racing sports that require high-performance clutch systems, such as drag racing, street racing, and racetracks.
Installation recommendations:
Since the clutch system uses a three-disc design and a lightweight flywheel, it is recommended that it be installed and adjusted by professional technicians to ensure optimal performance output and service life.
