Understanding - Adjustable Control Arms

Adjustable control arms are an essential upgrade for performance vehicles, offering increased suspension geometry control, alignment precision, and enhanced handling characteristics. This guide will help you understand the importance of installing adjustable control arms on your performance vehicle and how they can significantly improve your driving experience on the track or the street.

Understanding Adjustable Control Arms

Control arms, also known as A-arms or wishbones, are suspension components that connect the steering knuckle or wheel hub to the vehicle's frame or body. Adjustable control arms offer the ability to fine-tune various aspects of the suspension geometry, such as camber, caster, and toe. These adjustments allow for precise control of the vehicle's suspension settings, optimizing alignment, handling, and tire contact patch.

Importance of Installing Adjustable Control Arms on a Performance Vehicle

  1. Improved Suspension Geometry: One of the primary benefits of adjustable control arms is the ability to optimize your vehicle's suspension geometry. Proper suspension geometry is crucial for maintaining optimal tire contact with the road and ensuring maximum grip and handling performance. Adjustable control arms allow you to fine-tune camber, caster, and toe settings to suit your driving preferences and usage (e.g., track, autocross, or spirited street driving).

  2. Enhanced Handling and Grip: By offering greater control over suspension geometry, adjustable control arms can significantly improve your vehicle's handling and grip. Properly set up control arms can enhance cornering performance, vehicle stability, and overall driver confidence, allowing you to push your vehicle to its limits more safely and predictably.

  3. Reduced Tire Wear: Correctly aligned wheels promote even tire wear, prolonging the life of your tires and reducing the need for frequent replacements. Adjustable control arms enable precise alignment adjustments, which can help minimize excessive and uneven tire wear.

  4. Compatibility with Other Performance Upgrades: Adjustable control arms are often designed to work in conjunction with other performance upgrades, such as aftermarket sway bars, coilovers, and bushings. This compatibility allows you to create a comprehensive, high-performance suspension system that works in harmony to deliver the best possible results.

  5. Durability and Performance: Many adjustable control arms are constructed with high-strength materials, such as chromoly steel or aluminum, and feature heavy-duty bushings or spherical bearings. These materials and components can provide increased durability, reduced deflection, and improved performance compared to stock control arms.

Selecting the Right Adjustable Control Arms for Your Performance Vehicle

When choosing adjustable control arms for your performance vehicle, consider the following factors:

  1. Driving Style and Goals: Determine your priorities regarding handling, performance, and daily drivability. Different control arms offer varying levels of adjustability and performance capabilities, so it's essential to select a set that aligns with your needs and preferences.

  2. Vehicle Type and Suspension Setup: The ideal adjustable control arms will depend on your vehicle's specific suspension setup, weight distribution, and chassis characteristics. Consult with a suspension expert or your vehicle's manufacturer to determine the best control arms for your application.

  3. Installation and Maintenance: Ensure that the adjustable control arms you choose can be installed without significant modifications and are compatible with your vehicle's suspension system. Some control arms may require professional installation and regular maintenance, while others can be installed by experienced DIYers with the appropriate tools and knowledge.


Installing adjustable control arms on a performance vehicle can offer significant benefits in terms of handling, suspension geometry control, and overall performance. By providing the ability to fine-tune various suspension geometry aspects, adjustable control arms allow you to optimize your vehicle's handling and performance to suit your specific driving preferences and conditions. With their improved suspension geometry, enhanced handling and grip, reduced tire wear, compatibility with other performance upgrades, and increased durability, adjustable control arms are a valuable upgrade for any performance vehicle. Regular checks and adjustments are essential to maintain optimal performance, safety, and longevity of your upgraded suspension system.
