The Subaru WRX has long been a favorite among car enthusiasts, especially for those who enjoy track days and spirited driving. In this article, we will explore a comprehensive track-ready build for the VB WRX, focusing on installing coilovers, brakes, and power modifications to achieve over 400 horsepower.
Understanding the VB WRX
The VB WRX, introduced in 2021, represents a significant evolution in the WRX lineage. With its robust turbocharged engine and advanced all-wheel-drive system, it provides an excellent platform for performance upgrades. However, to truly excel on the track, modifications are necessary.
Coilover Installation
One of the first upgrades you should consider for your VB WRX is a set of coilovers. Coilovers not only improve handling but also allow for adjustable ride height, which is essential for track performance.
Choosing the Right Coilovers
When selecting coilovers, consider factors such as adjustability, spring rates, and build quality. Popular options for the VB WRX include:
- BC Racing BR Series
- KW Variant 3
- Fortune Auto 500 Series
Each of these offers a balance of performance and comfort, making them suitable for both track and street use.
Installation Steps
Installing coilovers can be a straightforward process if you follow these steps:
- Gather necessary tools: jack, jack stands, socket set, and a spring compressor.
- Lift the car and remove the wheels.
- Disconnect the strut assembly from the top mount and lower control arm.
- Remove the factory strut and replace it with the new coilover.
- Adjust the ride height to your preference and reassemble everything.
Ensure that you have a proper alignment done after installation to maintain handling characteristics.
Upgrading Brakes
With increased power and improved handling, upgrading your brakes is crucial for safety and performance. The stock brakes may not be sufficient for track use, so consider the following upgrades.
Brake Components to Upgrade
Key components to upgrade include:
- Brake pads
- Rotors
- Brake lines
- Master cylinder
High-performance brake pads and rotors will provide better stopping power and heat dissipation, while upgraded brake lines prevent expansion under pressure, ensuring a firm pedal feel.
Recommended Brake Kits
Consider these popular brake kits for your VB WRX:
- StopTech Sport Brake Kit
- Hawk Performance Brake Pads
- Project Mu Rotors
These kits are designed to withstand the rigors of track use while providing consistent performance.
Power Modifications for 400+ HP
To achieve over 400 horsepower, a combination of engine modifications and tuning is essential. Here are some effective upgrades to consider:
Turbocharger Upgrade
Upgrading the turbocharger is one of the most effective ways to increase horsepower. Options include:
- Garrett GTX3071R
- HKS GT II
- Blouch 20G-XTR
These turbochargers provide a significant boost in power and efficiency, especially when paired with proper tuning.
Fuel System Upgrades
To support higher horsepower, upgrading the fuel system is crucial. This includes:
- High-flow fuel injectors
- Upgraded fuel pump
- Fuel pressure regulator
These components ensure that your engine receives the necessary fuel for optimal performance.
ECU Tuning
After making hardware upgrades, proper ECU tuning is essential to maximize performance. Consider working with a reputable tuning shop that specializes in Subaru vehicles.
Conclusion
Building a track-ready VB WRX involves careful consideration of suspension, braking, and power modifications. By following the steps outlined above, you can create a vehicle that not only meets but exceeds your performance expectations on the track.
With the right upgrades, your WRX will be ready to tackle any track day with confidence and style. Happy driving!
