What is the primary benefit of a twin disc clutch over a single disc clutch?

A twin disc clutch uses two friction surfaces instead of one, which significantly increases the torque holding capacity. This design also helps to reduce the overall diameter and rotational mass of the clutch assembly, potentially improving engine response and allowing for more consistent engagement under high load.

What is the difference between a steel flywheel and a lighter flywheel option?

Steel flywheels are generally more durable and cost-effective, offering good heat dissipation for street and race use. Lighter flywheels can improve engine response by reducing rotational mass, but they may not be as durable for extreme track conditions and can sometimes make the vehicle more difficult to drive smoothly in stop-and-go traffic.

Does this clutch kit include everything needed for installation?

This kit includes the twin disc clutch assembly and the steel flywheel. It is recommended to consult the manufacturer's installation guide for a complete list of required components and any additional hardware or fluids that may be necessary for proper installation.

About this part

Product Details

The Clutch Masters 850 Series twin disc clutch assembly is built with steel friction surfaces, offering a robust solution for the 2005-2009 Audi S4 4.2L B7. This setup is engineered to handle the demands of both spirited street driving and track-focused racing, providing a significant upgrade over the stock clutch's torque capacity and engagement characteristics. The twin-disc design distributes the load across two friction surfaces, which not only increases holding power but also helps to reduce the rotational mass of the clutch assembly, potentially leading to improved engine response.

This particular kit features a steel flywheel, a durable and cost-effective choice that offers excellent heat dissipation for consistent performance during demanding use. The 850 Series is known for its ability to manage high horsepower and torque levels, making it a popular choice for S4 owners looking to significantly enhance their vehicle's drivetrain capabilities. The engagement is designed to be firm and predictable, providing a solid connection between the engine and the transmission, which is crucial for launching the car effectively and maintaining control during aggressive driving.

When installing a twin-disc clutch like this, it's important to follow the manufacturer's specific instructions carefully, as the setup and break-in procedure can differ from single-disc units. This Clutch Masters assembly is a well-built component designed to provide reliable performance for enthusiasts who push their vehicles hard. It represents a substantial upgrade for those seeking to maximize their S4's drivetrain efficiency and durability under extreme conditions.
