They are made from a blend of organic materials, sometimes adding brass, and provide a good balance between performance and daily drivability. Organic clutches offer smooth engagement, low pedal effort, and are suitable for most high-performance applications.

Medium Performance Clutch: Segmented Ceramic

Segmented Ceramic clutches are designed for medium-performance applications that require increased torque capacity. They are made from a mixture of ceramic materials and offer improved heat resistance and durability. Segmented ceramic clutches provide a more aggressive engagement and are ideal for vehicles with high horsepower and torque outputs.

Heavy Duty Performance Clutch: 6-Puck Ceramic

6-puck Ceramic clutches are higher version of the segmented ceramic clutches. They are designed for high-performance applications that require increased torque capacity than the above two applications. They are also made from a mixture of ceramic materials and offer improved heat resistance and durability. 6-puck ceramic clutches provide a more aggressive engagement and are ideal for applications such as drifting, dragging, and circuit racing.

Racing Clutch: Multi-disc Ceramic

Multi-disc clutches are designed for extreme high-performance applications. They feature multiple discs and offer the highest torque capacity of any clutch type. Multi-disc clutches provide lightning-fast gear changes and are commonly used in racing and track-oriented vehicles.

Factors to consider when choosing a performance clutch

Selecting the right performance clutch for your vehicle requires careful consideration of several factors. These factors will help ensure that you choose a clutch that is compatible with your vehicle’s power output, driving style, and intended use. Let’s take a closer look at the key factors you should consider when making your decision.

Torque Capacity: The torque capacity of a clutch refers to the maximum amount of torque it can handle without slipping. It is crucial to choose a clutch that can handle the torque output of your vehicle’s engine. Failure to do so can result in clutch slippage, reduced performance, and potential damage to the clutch and other drivetrain components.

Driving Style: Your driving style plays a significant role in determining the type of clutch that is best suited for you. If you engage in aggressive driving or participate in track events, a clutch with a higher torque capacity and more aggressive engagement may be ideal. On the other hand, if you primarily use your vehicle for daily commuting, a clutch with a smoother engagement and lower pedal effort may be more suitable.

Intended Use: Consider how you plan to use your vehicle. If you’re building a high-performance street car, a clutch that offers a good balance between performance and daily drivability is recommended. However, if you’re building a dedicated track car or drag racer, a clutch with a higher torque capacity and more aggressive engagement may be necessary to handle the demands of intense racing conditions.

Now that you have a better understanding of the factors to consider when choosing a performance clutch, let’s explore the impact of clutch materials on performance.

Materials and their impact on performance clutch

The material used in a performance clutch greatly influences its overall performance and durability. Different materials offer varying levels of heat resistance, friction characteristics, and wear resistance. Understanding the properties of different clutch materials will help you make an informed decision when selecting a clutch for your vehicle.

Pressure Material: Diaphragm Spring 65Mn vs 51CrV4

The diaphragm spring of a clutch pressure plate is a key component ensuring the proper functioning of the clutch, directly affecting the engagement and disengagement of the clutch. In terms of material selection, 65Mn and 51CrV4 are two common options, each with their distinct characteristics and suitable applications.

65Mn is a type of high-carbon spring steel containing a certain proportion of manganese, providing good strength and hardness.

  • Advantages: The main advantages of 65Mn include high strength, good elasticity, and excellent wear resistance. This makes it suitable for diaphragm springs that require higher strength and durability.
  • Applications: For standard to medium-load automotive clutches, 65Mn is an economical and effective choice.


51CrV4 is a superior grade of spring steel containing elements of chromium and vanadium, which endow it with enhanced mechanical properties and heat resistance.

  • Characteristics: 51CrV4 maintains good strength and toughness even at high temperatures, which is crucial for clutch pressure plates in high-performance or heavy-load applications.
  • Usage: For high-performance vehicles, heavy-duty vehicles, or clutches operating under extreme conditions, 51CrV4 is a more suitable choice.


Material Comparison

  • Strength and Wear Resistance: Although both materials have good strength and wear resistance, 51CrV4 performs better under extreme conditions.
  • Heat Resistance: 51CrV4 has notably better heat resistance than 65Mn, which is particularly important in high-temperature environments.

Friction Material: Organic vs Ceramic

Clutches made from organic materials, offer a good balance between performance and daily drivability. They provide smooth engagement, low pedal effort, and are suitable for most high-performance applications. However, organic clutches have a limited lifespan and may not withstand the high heat generated by extreme racing conditions.

Ceramic clutches are designed for high-performance applications that require increased torque capacity. They are made from a mixture of ceramic materials and offer improved heat resistance and durability. Ceramic clutches provide a more aggressive engagement and are ideal for vehicles with high horsepower and torque outputs. However, they can be harsher on the drivetrain and may require a break-in period to optimize performance.

Casting Material: Ductile Iron vs Gray Iron

Ductile iron and gray iron each have their unique advantages in the application of clutch pressure plates. Clutch pressure plates used in high-performance cars and racing vehicles require materials with superior wear resistance and load-bearing capacity, especially those that can excel under impact and stress.

Ductile iron is a type of high-strength cast iron, primarily characterized by its spherical graphite content. This structure endows ductile iron with higher strength and toughness while maintaining a certain level of ductility. Ductile iron surpasses grey iron in terms of strength and durability, and due to its high strength, it can even be designed thinner, thus reducing weight. This reduction in weight is beneficial for enhancing vehicle performance and fuel efficiency.

Gray iron, containing flake graphite, displays good compressive strength and shock absorption capacity but has less ductility. It is suitable for standard vehicle clutch pressure plates, especially under normal driving conditions, providing sufficient performance and durability.
