Key Suspension Upgrade Options for the 2020 Acura TLX

1. Coilover Kits

Coilover suspension kits are one of the most popular upgrades for performance enthusiasts. These assemblies combine springs and shock absorbers into a single unit, often with adjustable ride height and damping settings.

  • Adjustability: Coilovers typically allow you to lower the car, reducing its center of gravity for improved cornering. Many kits also offer adjustable compression and rebound damping, so you can tune the firmness of the ride, from comfortable to track-ready.
  • Improved Handling: By stiffening the suspension and reducing body roll, coilovers provide a more planted feel on curves and during spirited driving.
  • Examples: Popular brands such as KW, Bilstein, and Tein offer coilover kits designed specifically for the Acura TLX with tailored valving and spring rates.

2. Sway Bars (Anti-Roll Bars)

Sway bars connect the left and right wheels through a torsion spring to resist body roll during cornering. Upgrading to thicker sway bars can dramatically improve handling balance.

  • Reduced Body Roll: Thicker sway bars increase resistance to leaning in corners, keeping the vehicle flatter and tires in better contact with the road.
  • Improved Responsiveness: Enhanced sway bars provide quicker transitions through turns and more predictable vehicle behavior.
  • Front vs. Rear: Adjusting sway bar stiffness at either end affects understeer or oversteer characteristics, allowing fine-tuning of the TLX’s handling balance.

3. Performance Springs

Lowering springs replace the factory springs with shorter, stiffer versions that lower the ride height and improve handling without the complexity of a full coilover setup.

  • Lower Center of Gravity: Reducing ride height decreases body roll and improves cornering stability.
  • Aggressive Stance: Lowering springs enhance the visual appeal by closing the wheel gap for a sportier look.
  • Cost-Effective: Springs are generally less expensive than coilovers and easier to install.
  • Considerations: Because springs do not include adjustable damping, pairing them with upgraded shocks or struts is recommended to prevent a harsh ride.

4. Strut Tower Braces

Strut tower braces connect the top of the front or rear strut towers to increase chassis rigidity, which helps maintain suspension geometry during aggressive driving.

  • Improved Steering Precision: Reduced flex in the chassis allows the suspension to work more effectively, enhancing steering response.
  • Enhanced Cornering Stability: By preventing unwanted movement in the strut towers, braces help maintain tire contact patches during cornering.
  • Simple Installation: Most strut braces bolt directly onto existing strut tower mounting points and can be installed with basic tools.

5. Upgraded Shock Absorbers and Struts

While stock shocks and struts are designed for a balance of comfort and performance, upgrading to performance-oriented dampers can provide better control over suspension movement.

  • Improved Damping: Performance shocks offer better resistance to compression and rebound, reducing body oscillations and improving stability.
  • Compatibility with Springs: Upgraded shocks are especially important when paired with lowering springs to prevent the suspension from becoming too harsh or bouncy.
  • Options: Adjustable shocks allow fine-tuning of ride quality and handling characteristics.

Additional Suspension Enhancements

Bushing Upgrades

Replacing factory rubber suspension bushings with polyurethane or solid bushings reduces compliance in suspension linkages, improving precision and feedback. This can enhance overall handling feel but may increase noise and vibration transmitted to the cabin.

Camber Kits

Adjustable camber kits allow fine-tuning of wheel alignment settings, particularly camber angle, which affects tire contact patch during cornering. This is especially useful for track or performance driving to maximize grip and tire wear.

Wheel and Tire Considerations

Suspension upgrades should be complemented by appropriate wheel and tire choices. Wider, stickier tires improve grip and handling, while lightweight wheels reduce unsprung weight, enhancing suspension responsiveness.
