The Subaru WRX has long been a favorite among car enthusiasts for its performance and rally heritage. With a powerful engine and all-wheel drive, it offers an exhilarating driving experience. However, to truly maximize its potential, modifications are often necessary. One such modification that has gained popularity is the installation of Energy Suspension bushings. In this article, we will explore the real-world results of upgrading to Energy Suspension bushings on a 450 HP Subaru WRX.
Understanding Energy Suspension Bushings
Energy Suspension bushings are designed to replace the factory rubber bushings in vehicles. These polyurethane bushings provide several benefits over traditional rubber, including:
- Improved Handling: Polyurethane bushings offer better stiffness and responsiveness, enhancing the overall handling of the vehicle.
- Durability: Unlike rubber, polyurethane is resistant to deterioration from oil, grease, and road salt, leading to a longer lifespan.
- Reduced Noise and Vibration: While they are firmer, Energy Suspension bushings can also help minimize unwanted noise and vibrations from the road.
The 450 HP Subaru WRX: A Performance Overview
The Subaru WRX is known for its turbocharged flat-four engine, which delivers impressive power and torque. In this case, we are focusing on a modified WRX that has been tuned to produce 450 horsepower. This level of power requires precise handling and stability, especially during aggressive driving or track use. Without upgraded components, the factory bushings can lead to a less than optimal driving experience.
Before Installation: Stock Performance
Before the installation of Energy Suspension bushings, the WRX exhibited several performance characteristics:
- Body Roll: The factory bushings allowed for excessive body roll during cornering, which compromised handling and driver confidence.
- Steering Response: There was noticeable vagueness in the steering feel, making it difficult to gauge the vehicle’s traction limits.
- Vibration and Noise: The stock bushings transmitted more road noise and vibrations into the cabin, detracting from the driving experience.
Installation of Energy Suspension Bushings
The process of installing Energy Suspension bushings involves removing the factory bushings and replacing them with new polyurethane options. This typically requires:
- Tools Needed: A jack, jack stands, wrenches, and possibly a press for stubborn bushings.
- Time Investment: Depending on experience, the installation can take several hours to complete.
- Expert Assistance: For those unfamiliar with suspension work, consulting a professional mechanic is advisable.
After Installation: Performance Improvements
After the installation of Energy Suspension bushings, the Subaru WRX exhibited significant performance improvements:
- Enhanced Handling: The reduction in body roll allowed for sharper cornering and improved stability during high-speed maneuvers.
- Better Steering Feedback: The steering response became more direct, providing the driver with better control and confidence.
- Reduced Noise and Vibration: The new bushings effectively dampened unwanted noise and vibrations, resulting in a more comfortable ride.
Real-World Driving Experience
Drivers reported a noticeable difference in the overall driving experience after upgrading to Energy Suspension bushings. The WRX felt more composed and agile, especially during spirited driving on winding roads and track days. Here are some firsthand accounts:
- Track Performance: On the track, the WRX demonstrated improved lap times and more predictable handling characteristics.
- Daily Driving: For daily commuters, the enhanced ride quality made the WRX more enjoyable and less fatiguing over long distances.
- Off-Road Capability: Enthusiasts noted that the improved suspension response also benefited off-road performance, allowing for better control on rough terrain.
Conclusion: The Value of Upgrading Bushings
The upgrade to Energy Suspension bushings on a 450 HP Subaru WRX proves to be a valuable investment for performance enthusiasts. With enhanced handling, improved steering feedback, and reduced noise, drivers can enjoy a more engaging and comfortable driving experience. Whether on the track or the road, these bushings help unlock the full potential of the WRX, making it a more capable and enjoyable vehicle.
Final Thoughts
For those considering modifications to their Subaru WRX, upgrading to Energy Suspension bushings is highly recommended. The transformation in performance and driving dynamics is significant, making it a worthwhile addition to any performance build.
