When it comes to modifying a Subaru WRX for performance, handling and suspension upgrades are just as crucial as engine enhancements. A powerful engine can only perform optimally if the vehicle’s suspension can handle the increased power and provide better control. This article explores essential handling and suspension upgrades for aggressive WRX builds.
Understanding the Importance of Suspension Upgrades
Upgrading the suspension system of a WRX is vital for several reasons:
- Improved Handling: Better suspension components provide enhanced grip and cornering capabilities.
- Increased Stability: Upgrades help maintain stability at high speeds and during aggressive driving.
- Enhanced Comfort: Modern suspension systems can improve ride comfort without sacrificing performance.
Key Suspension Components to Upgrade
Several components of the suspension system can be upgraded to achieve optimal performance for a built engine:
- Coilovers: Adjustable coilovers allow for fine-tuning of ride height and damping settings.
- Sway Bars: Upgrading sway bars can reduce body roll during cornering.
- Strut Braces: Strut braces improve chassis rigidity and help maintain alignment during hard cornering.
- Control Arms: Upgraded control arms can enhance suspension geometry and improve handling.
Choosing the Right Coilovers
Coilovers are one of the most significant upgrades for a WRX. When selecting coilovers, consider the following:
- Adjustability: Look for coilovers that offer adjustable ride height and damping settings.
- Spring Rates: Choose spring rates that match your driving style and intended use.
- Quality Brands: Brands like BC Racing, KW, and Tein are known for their performance coilovers.
Upgrading Sway Bars
Sway bars play a crucial role in reducing body roll and improving cornering stability. Here are some tips for upgrading sway bars:
- Thickness: Thicker sway bars provide more resistance to body roll.
- Adjustable Options: Consider adjustable sway bars to fine-tune your vehicle’s handling characteristics.
- Material: Look for sway bars made from high-quality materials for durability.
Installing Strut Braces
Strut braces help to increase chassis stiffness, which can improve handling. Here’s what to keep in mind:
- Types: Options include front and rear strut braces, as well as lower braces.
- Material: Aluminum and steel strut braces offer different levels of strength and weight savings.
- Fitment: Ensure the strut brace fits your specific WRX model for optimal performance.
Upgrading Control Arms
Control arms affect suspension geometry and can lead to improved handling. Consider the following when upgrading:
- Material: Lightweight aluminum control arms can reduce unsprung weight.
- Design: Look for control arms that offer improved angles for better handling.
- Adjustability: Adjustable control arms allow for fine-tuning of camber and caster settings.
Aligning Your WRX After Upgrades
After installing suspension upgrades, a proper alignment is essential. Here’s why:
- Performance: Correct alignment ensures optimal tire contact with the road.
- Tire Wear: Proper alignment helps prevent uneven tire wear.
- Handling: Alignment affects handling characteristics and overall driving experience.
Maintaining Your Upgraded Suspension
To ensure longevity and optimal performance of your upgraded suspension, regular maintenance is key:
- Inspection: Regularly inspect components for signs of wear or damage.
- Lubrication: Keep moving parts lubricated to prevent wear.
- Re-evaluation: Periodically assess your setup to ensure it meets your driving needs.
Conclusion
Upgrading the handling and suspension of your aggressive WRX build is essential for maximizing performance and ensuring a thrilling driving experience. By focusing on key components like coilovers, sway bars, strut braces, and control arms, you can enhance your vehicle’s capabilities. Remember to maintain your upgrades and perform regular alignments to keep your WRX performing at its best.
