The Subaru WRX has long been a favorite among performance enthusiasts, and for good reason. The combination of turbocharged power and all-wheel drive makes it a formidable contender on both the street and the track. However, to maximize its potential, especially in high-performance scenarios, upgrading the drivetrain components is essential. This article will explore key performance upgrades for the VB WRX, focusing on clutches, differentials, and axle improvements.
Understanding the Importance of Drivetrain Upgrades
Drivetrain upgrades are crucial for enhancing the performance of your WRX. They can improve power transfer, increase traction, and enhance overall driving experience. Here are some reasons why upgrading your drivetrain is important:
- Power Handling: Stock components may not handle increased power from modifications.
- Traction Improvement: Upgraded parts can help manage power delivery to the wheels.
- Durability: Performance parts are designed to withstand higher stress levels.
Clutch Upgrades for the VB WRX
The clutch is one of the most critical components in the drivetrain, especially for performance vehicles. Upgrading the clutch can lead to better engagement and increased power handling. Here are some popular options:
- Stage 1 Clutch: Ideal for mild power upgrades, offering better engagement without sacrificing daily drivability.
- Stage 2 Clutch: Suitable for moderate power increases, featuring a higher clamping force for improved performance.
- Stage 3 Clutch: Designed for high horsepower builds, this clutch offers maximum grip and is best for track use.
Benefits of Upgrading the Clutch
Upgrading the clutch provides several benefits, including:
- Improved Shifting: Enhanced feel and precision during gear changes.
- Increased Longevity: Performance clutches are built to last under high-stress conditions.
- Better Power Transfer: More efficient transfer of power from the engine to the drivetrain.
Differential Upgrades for Enhanced Traction
The differential plays a vital role in managing power distribution to the wheels. Upgrading the differential can significantly improve traction and handling. Here are some options to consider:
- Limited Slip Differential (LSD): Helps improve traction by distributing power to the wheel with the most grip.
- Center Differential Upgrade: Enhances the torque distribution between the front and rear wheels for better stability.
- Aftermarket Differential Covers: Improve heat dissipation and provide additional strength.
Advantages of Differential Upgrades
Upgrading your differential can lead to several advantages, such as:
- Improved Cornering: Better power distribution leads to enhanced cornering performance.
- Increased Stability: A well-matched differential setup provides better control during aggressive driving.
- Enhanced Traction: More effective power delivery results in improved acceleration.
Axle Improvements for Strength and Performance
Upgrading the axles is essential for handling increased power and torque. Stock axles may fail under high-stress conditions, making it crucial to consider aftermarket options. Here are some notable upgrades:
- Performance Axles: Designed to handle higher power levels and provide better durability.
- Heavy-Duty CV Joints: Improve strength and reduce the risk of failure during aggressive driving.
- Lightweight Axles: Reduce unsprung weight for improved handling and responsiveness.
Benefits of Upgrading Axles
Enhancing your axles can yield numerous benefits, including:
- Increased Reliability: Stronger components reduce the likelihood of breakage.
- Better Performance: Improved power handling translates to better acceleration and handling.
- Enhanced Driving Experience: A more responsive setup enhances overall driving enjoyment.
Conclusion
Upgrading the drivetrain of your VB WRX is a vital step in maximizing its performance potential. By investing in high-quality clutches, differentials, and axles, you can enhance power delivery, improve traction, and ensure reliability under demanding conditions. Whether you’re a daily driver or a track enthusiast, these upgrades will significantly enhance your driving experience.
