Enhancing your Mitsubishi ASX by installing a strut tower brace is one of the most effective and accessible modifications to improve your vehicle's handling dynamics. This upgrade strengthens the chassis, reducing flex during cornering and providing a more connected and responsive driving experience. Whether you are an enthusiast seeking better control on twisty roads or simply want to enhance everyday driving confidence, a strut tower brace offers noticeable benefits without the complexity or cost of more extensive suspension modifications.

Understanding the Role of a Strut Tower Brace

The strut tower brace is a structural component that links the two front strut towers located in the engine bay. These towers are critical mounting points for your suspension’s upper struts, which absorb shocks and maintain tire contact with the road. Under hard cornering or uneven surfaces, the chassis can experience flex and distortion as the strut towers move independently, which can lead to less precise steering and reduced stability.

By bridging the gap between the strut towers, the brace distributes forces more evenly across the front of the vehicle, effectively stiffening the chassis. This reinforcement minimizes chassis flex, maintaining the intended suspension geometry and improving the responsiveness of your steering input. The result is enhanced cornering stability, better road feedback, and a generally more planted feel.

Benefits of Installing a Strut Tower Brace on the Mitsubishi ASX

  • Improved Handling Precision: Reduced chassis flex means your suspension components work as designed, increasing steering accuracy and allowing for more confident cornering.
  • Enhanced Stability: The brace contributes to a more rigid front end, which helps the vehicle maintain composure during sudden maneuvers or on uneven roads.
  • Preservation of Suspension Geometry: By limiting movement of the strut towers, the suspension maintains optimal alignment settings for better tire contact and wear.
  • Simple and Cost-Effective Upgrade: Compared to full suspension overhauls, installing a strut tower brace is relatively affordable and straightforward.
  • Increased Driver Confidence: A more predictable and responsive driving experience can make everyday driving more enjoyable and safer.

Choosing the Right Strut Tower Brace for Your ASX

Before you begin the installation process, it’s important to select a brace that suits your needs and preferences. Several options are available on the market, ranging from OEM-style braces to high-performance aftermarket pieces crafted from lightweight alloys such as aluminum or steel. Here are some considerations to help you choose the right one:

  • Material: Steel braces provide excellent strength but add weight, while aluminum braces offer a lighter alternative with good rigidity.
  • Design: Some braces feature adjustable or removable center sections to accommodate engine bay modifications or cosmetic preferences.
  • Finish: Powder-coated or anodized finishes help prevent corrosion and add a polished look under the hood.
  • Compatibility: Ensure the brace is specifically designed for the Mitsubishi ASX to guarantee proper fitment and mounting.
  • Brand Reputation: Opt for reputable manufacturers known for quality and durability to avoid issues such as poor fit or premature wear.

Tools and Preparation Required for Installation

Installing a strut tower brace is a relatively simple task that can be accomplished with basic mechanical tools and some attention to detail. Here’s what you’ll need to prepare before starting:

  • Socket Set: To remove and reinstall the nuts on the strut towers, ensure you have the correct socket sizes, typically 12mm or 14mm for the ASX.
  • Torque Wrench: Essential for tightening the nuts to the manufacturer’s recommended torque settings, preventing overtightening or under-tightening.
  • Jack and Jack Stands (Optional): While often not necessary, raising the front of the vehicle can improve access and visibility inside the engine bay.
  • Gloves and Safety Glasses: Protect your hands and eyes during the installation process.
  • Service Manual or Installation Instructions: Reference your vehicle’s manual or the brace manufacturer’s guide for specific torque values and procedures.

Step-by-Step Installation Guide

Step 1: Park and Prepare Your Vehicle

Park your Mitsubishi ASX on a flat, stable surface and engage the parking brake. Ensure the engine is off and cool before opening the hood to prevent burns or injuries.

Step 2: Locate the Strut Towers

Open the hood and locate the two front strut towers on either side of the engine bay, near the fenders. These towers feature three studs each, secured with nuts that hold the suspension struts in place.

Step 3: Remove the Nuts on the Strut Towers

Using your socket set, carefully remove the three nuts from each strut tower one at a time. It’s important to keep track of these nuts as you will reuse them to secure the brace.

Step 4: Position the Strut Tower Brace

Place the strut tower brace over the strut towers, aligning the holes in the brace with the studs on each tower. The brace should sit flush over the towers without any gaps or interference with other components.

Step 5: Reinstall and Tighten the Nuts

Hand-thread the nuts back onto the studs to secure the brace in place. Then, using your torque wrench, tighten each nut evenly in a crisscross pattern to the manufacturer’s specified torque setting, usually around 35 to 45 Nm (check your manual or brace instructions for exact values).

Step 6: Verify Installation

Double-check that all nuts are properly tightened and that the brace is firmly secured. Inspect for any clearance issues with hoses, wiring, or engine components to ensure nothing is pinched or stressed.

Post-Installation Considerations

After installing the strut tower brace, it’s a good idea to take your Mitsubishi ASX for a test drive to experience the improvements firsthand. Pay attention to the following:

  • Steering Response: Notice if the steering feels more direct and responsive, especially when entering and exiting corners.
  • Body Roll: Observe whether the car feels more stable and composed during lateral movements.
  • No Unusual Noises: Listen for any rattles or creaks that may indicate loose fasteners or improper fitment.

If you detect any issues, stop and inspect the installation to correct any problems before continuing to drive.

Additional Tips for Maximizing Performance

While a strut tower brace significantly improves chassis rigidity, combining it with other suspension upgrades can further enhance your ASX’s handling:

  • Upgraded Sway Bars: Reducing body roll with stiffer anti-roll bars complements the brace’s effects.
  • Performance Shock Absorbers and Springs: Tailoring suspension components to your driving style will enhance overall road-holding.
  • Wheel Alignment: After modifications, getting a professional alignment ensures optimal tire contact and suspension geometry.
  • Lightweight Wheels and Performance Tires: Reducing unsprung weight and improving grip magnifies the benefits of a stiffer chassis.

Common Questions About Strut Tower Braces

Will a Strut Tower Brace Affect Ride Comfort?

Typically, a strut tower brace does not negatively impact ride comfort because it primarily increases chassis rigidity without altering the suspension’s compliance. You can expect better handling without a harsher ride.

While the installation is straightforward for those comfortable with basic tools, if you are uncertain or lack the necessary equipment, seeking professional assistance ensures proper fitment and safety.

Can I Install a Strut Tower Brace on Rear Strut Towers?
