The Subaru WRX is a popular choice for performance enthusiasts, and upgrading its handling capabilities can significantly enhance the driving experience. When considering upgrades, particularly with the addition of a Flex Fuel Kit, it is crucial to focus on both suspension and braking enhancements. This article will guide you through the essential upgrades that can optimize your WRX’s handling.
Understanding the Flex Fuel Kit
A Flex Fuel Kit allows your WRX to run on both regular gasoline and ethanol-based fuels, which can improve performance and efficiency. The ability to adjust fuel maps and take advantage of higher ethanol content can lead to increased horsepower and torque. However, to fully benefit from this upgrade, you must also enhance your suspension and braking systems.
Suspension Upgrades
Upgrading the suspension is vital for improving handling, stability, and ride comfort. Here are some key components to consider:
- Coilovers: Adjustable coilovers allow you to lower the car’s center of gravity and fine-tune the ride height and damping settings.
- Sway Bars: Upgrading to stiffer sway bars can reduce body roll during cornering, providing a more planted feel.
- Control Arms: Aftermarket control arms can improve alignment settings and enhance overall suspension geometry.
- Strut Braces: Adding strut braces can increase chassis rigidity, leading to better handling and response.
Coilover Systems
Coilover systems are a popular choice among WRX owners. They provide the ability to adjust ride height and damping, allowing for a custom setup that matches your driving style. Consider brands like BC Racing or Fortune Auto for quality options.
Sway Bar Installation
Installing upgraded sway bars can dramatically improve cornering performance. A larger diameter sway bar will help reduce body roll, making the car feel more stable during aggressive driving. Look for options from manufacturers like Whiteline or Eibach.
Braking Enhancements
With increased performance from the Flex Fuel Kit and suspension upgrades, enhancing your braking system is essential for safety and performance. Consider the following upgrades:
- Brake Pads: Upgrading to high-performance brake pads can improve stopping power and reduce brake fade.
- Rotors: Slotted or drilled rotors can enhance heat dissipation, improving braking performance during extreme conditions.
- Brake Lines: Stainless steel braided brake lines can offer better pedal feel and reduce flex under hard braking.
- Calipers: Upgrading to larger calipers can increase clamping force, resulting in shorter stopping distances.
Choosing the Right Brake Pads
Selecting the right brake pads is crucial for achieving optimal performance. Look for pads that are designed for your specific driving needs, whether it’s daily driving, track use, or spirited driving. Brands like Hawk and Ferodo offer a range of options to suit different applications.
Upgrading Rotors
When upgrading rotors, consider slotted or drilled options for improved performance. These designs help dissipate heat and reduce the likelihood of brake fade during intense driving. Performance rotors from brands like DBA or StopTech are excellent choices.
Conclusion
Upgrading your WRX with a Flex Fuel Kit is an excellent way to boost performance, but it’s essential to complement this upgrade with suspension and braking enhancements. By investing in quality components, you can significantly improve handling, stability, and safety, making your driving experience more enjoyable. Whether you’re tackling the track or navigating winding roads, these upgrades will help your WRX perform at its best.
