When turbocharging your WRX to achieve 400+ horsepower, selecting the right clutch becomes crucial for maximizing grip and performance. This article will guide you through the essential considerations for clutch selection in a turbocharged Subaru WRX.

Understanding Clutch Functionality

A clutch is a vital component that connects and disconnects the engine from the transmission. In high-performance applications, the clutch must handle increased power and torque while providing smooth engagement and disengagement. Understanding how clutches work will help you make an informed choice.

Types of Clutches

There are several types of clutches available for the Subaru WRX, each with its unique characteristics. Here are the main types:

  • Organic Clutch: Provides smooth engagement, ideal for daily driving.
  • Performance Clutch: Designed for higher power levels, offering improved grip and durability.
  • Button Clutch: Offers maximum grip, suitable for racing applications but can be harsh for street use.
  • Twin Disc Clutch: Provides increased surface area for better grip, ideal for high horsepower setups.

Key Factors to Consider

When selecting a clutch for your turbocharged Subaru WRX, consider the following factors:

  • Power Rating: Ensure the clutch can handle your power output without slipping.
  • Driving Style: Choose a clutch that aligns with your driving habits—street, track, or a mix of both.
  • Material: The material of the clutch disc affects its performance and longevity.
  • Pedal Feel: Some clutches offer a heavier pedal feel, which may not be suitable for all drivers.

Here are some recommended clutch options for turbocharged Subaru WRXs producing over 400 horsepower:

Installation Considerations

Proper installation of the clutch is critical to its performance and longevity. Consider the following during installation:

  • Flywheel Condition: Inspect and, if necessary, replace the flywheel to ensure proper engagement.
  • Torque Specifications: Follow manufacturer specifications for torque settings to avoid issues.
  • Break-In Period: Allow the clutch to break in properly to achieve optimal performance.

Maintaining Your Clutch

Regular maintenance is essential for extending the life of your clutch. Here are some maintenance tips:

  • Check Fluid Levels: Ensure the clutch fluid is at appropriate levels to maintain hydraulic pressure.
  • Avoid Riding the Clutch: This can cause unnecessary wear and reduce lifespan.
  • Listen for Noises: Unusual sounds during engagement may indicate issues that need addressing.

Conclusion

Selecting the right clutch for your turbocharged Subaru WRX is vital for maximizing grip and performance at 400+ horsepower. By understanding the types of clutches available, considering key factors, and following proper installation and maintenance practices, you can ensure your WRX performs at its best. Whether you choose an organic, performance, button, or twin disc clutch, make sure it aligns with your driving style and power goals.
