The Subaru WRX is a beloved vehicle among car enthusiasts, known for its rally heritage and impressive performance. However, to truly unlock its potential, upgrades are often necessary. One such upgrade that can significantly enhance power and handling is the installation of a Quaife ATB differential. This article explores the benefits of bushing upgrades and how a Quaife ATB diff can help boost your Subaru WRX to an impressive 350 horsepower.
Understanding the Importance of Bushings
Bushings are critical components in a vehicle’s suspension and drivetrain systems. They serve as cushions between metal parts, helping to absorb vibrations and reduce noise. Upgrading bushings can lead to improved performance in several ways:
- Enhanced Stability: Upgraded bushings provide better support and stability during cornering.
- Improved Handling: Stiffer bushings can lead to more responsive steering and handling characteristics.
- Reduced Wear: High-quality bushings can decrease wear on other suspension components.
What is a Quaife ATB Differential?
The Quaife ATB (Automatic Torque Biasing) differential is a popular upgrade for performance vehicles, including the Subaru WRX. Unlike traditional open differentials, the Quaife ATB diff utilizes gears to distribute torque between the wheels, providing several advantages:
- Improved Traction: The differential allows for better power distribution, enhancing traction during acceleration.
- Better Cornering: By managing wheel speed differences, it helps maintain stability and control while cornering.
- Durability: The robust design of the Quaife ATB diff ensures longevity and reliability under high-performance conditions.
Benefits of Combining Bushing Upgrades with a Quaife ATB Diff
When you combine bushing upgrades with a Quaife ATB differential, the benefits can be even more pronounced. Here are some key advantages:
- Synergistic Performance: Upgraded bushings complement the improved traction of the Quaife diff, resulting in enhanced overall performance.
- Increased Power Transfer: The combination allows for more efficient power transfer to the wheels, helping to reach that 350 hp mark.
- Enhanced Driving Experience: Together, these upgrades provide a more engaging and responsive driving experience.
Steps to Upgrade Your Subaru WRX
1. Choose the Right Bushings
Selecting the appropriate bushings is crucial for maximizing performance. Consider options such as polyurethane or solid bushings, which offer increased stiffness and durability.
2. Install the Quaife ATB Differential
Installing the Quaife ATB diff requires some mechanical knowledge. It’s advisable to consult a professional mechanic if you are unfamiliar with differential installation.
3. Align the Suspension
After installation, ensure that the suspension is properly aligned. This step is essential to maintain handling characteristics and tire wear.
Considerations Before Upgrading
Before proceeding with these upgrades, consider the following:
- Budget: Upgrades can vary in cost, so plan your budget accordingly.
- Skill Level: Assess your mechanical skills to determine if you can perform the upgrades yourself.
- Future Modifications: Consider how these upgrades fit into your overall performance goals for your Subaru WRX.
Conclusion
Upgrading the bushings and installing a Quaife ATB differential can significantly enhance the performance of your Subaru WRX, helping you achieve that coveted 350 horsepower. With improved traction, handling, and overall driving experience, these modifications are well worth considering for any performance enthusiast.
