Diy Suspension Swap on the Scion Fr-s: Improve Handling for Less Than $800

by

The Scion FR-S is a beloved sports car known for its lightweight chassis and engaging driving dynamics. However, many owners find that the factory suspension can be improved for better handling and performance. In this guide, we will explore a DIY suspension swap that can enhance your FR-S’s handling for less than $800.

Understanding Suspension Systems

Before diving into the swap, it’s essential to understand the components of a suspension system. The main parts include:

  • Shocks/Struts: These dampen the impact of bumps and help maintain tire contact with the road.
  • Coil Springs: These support the weight of the vehicle and absorb shocks from the road.
  • Control Arms: These connect the suspension to the chassis and allow for movement during driving.
  • Anti-roll Bars: These reduce body roll during cornering, improving stability.

Choosing the Right Suspension Components

When selecting suspension components for your Scion FR-S, consider the following options:

  • Coilovers: Adjustable coilovers provide customization for ride height and damping. Brands like BC Racing and Fortune Auto offer great options.
  • Spring and Shock Combo: If you prefer a simpler setup, consider a combination of lowering springs and performance shocks from brands like Eibach or Bilstein.
  • Anti-roll Bars: Upgrading to stiffer sway bars can further enhance handling and reduce body roll.

Tools and Materials Needed

For the DIY suspension swap, you will need the following tools and materials:

  • Tools:
    • Jack and jack stands
    • Socket set
    • Wrench set
    • Spring compressor (if using coil springs)
    • Torque wrench
  • Materials:
    • New suspension components (coilovers, shocks, springs)
    • New hardware (if required)
    • Lubricant or anti-seize compound

Steps for the Suspension Swap

Now that you have your tools and materials ready, follow these steps to complete your suspension swap:

  • Step 1: Park your FR-S on a flat surface and engage the parking brake. Loosen the lug nuts on the front wheels.
  • Step 2: Use the jack to lift the front of the car and secure it with jack stands. Remove the front wheels.
  • Step 3: Remove the old struts by unbolting them from the top mount and lower control arm. If using coil springs, compress them before removing.
  • Step 4: Install the new struts or coilovers. Ensure they are securely bolted in place.
  • Step 5: Reinstall the wheels and lower the car back to the ground. Repeat the process for the rear suspension.
  • Step 6: Once all components are installed, torque all bolts to the manufacturer’s specifications.

Testing Your New Suspension

After completing the installation, it’s crucial to test your new suspension setup. Here’s how to do it:

  • Alignment: Get a professional alignment to ensure proper handling and tire wear.
  • Test Drive: Take your FR-S for a test drive. Pay attention to how it handles corners and responds to bumps.
  • Adjustments: If you installed adjustable coilovers, fine-tune the ride height and damping settings to your preference.

Conclusion

Upgrading the suspension on your Scion FR-S can significantly improve its handling and overall driving experience. With the right components and a bit of DIY spirit, you can enhance your car’s performance for less than $800. Enjoy your newly transformed ride!
