What’s the Best Way to Improve the Handling of a Ford Mustang GT with Lowering Springs?

As you explore paths to optimize the performance of your Ford Mustang GT, you might come across varying opinions on car forums. Enthusiasts might suggest upgrades ranging from tires to shocks, but one common reply that often pops up is the use of lowering springs. Lowering springs can indeed offer a significant improvement in your Mustang’s handling. But how exactly do they work, and what should you consider when incorporating them into your car? Let’s dive into the intricate details of this popular modification.

Understanding the Basics of Lowering Springs

Before delving into the nuts and bolts of how to boost your Mustang’s handling with lowering springs, it’s essential to understand what lowering springs are and how they influence your car’s overall performance.

Lowering springs are the springs in your car’s suspension system that are designed to lower your car’s ride height. This reduction in height can result in better handling because it lowers the car’s center of gravity, increases aerodynamics, and reduces body roll.

The lowering springs work in conjunction with the shocks and struts in your car’s suspension system to absorb road bumps and maintain tire contact with the road. The result is a smooth, controlled ride, even at high speeds or during sharp turns.

Despite these benefits, modifying your Ford Mustang GT with lowering springs is not as simple as it might seem. You must consider several things, like the quality of the springs, the ride comfort, and the effects on the car’s other components.

Choosing the Right Lowering Springs

The market is flooded with an array of lowering springs, each promising an improved driving experience. However, not all springs are created equal. Some deliver a perfect blend of performance and comfort, while others might compromise ride quality for aggressive lowering.

High-quality lowering springs will offer a stiffer ride compared to stock springs, which is good for reducing body roll and improving handling. However, this should not sacrifice ride comfort. You want springs designed to provide a firm but not harsh ride.

When choosing lowering springs, consider the front and rear drop they offer. A balanced drop, often between 1 to 2 inches, will maintain the car’s aesthetics and ensure the tires have ample room for movement without rubbing against the wheel well. Remember, a drastic drop might look impressive, but it can lead to a bumpy ride and damage to the car’s underbody.

Integrating Lowering Springs with Other Suspension Components

To get the most out of your lowering springs, you need to ensure they work in harmony with other suspension components. In the car world, it’s often said that "everything affects everything". This statement is especially true for the suspension system.

When you lower your Mustang, it will affect the angle of the car’s driveshaft, which can lead to premature wear if not corrected. Therefore, it’s crucial to install adjustable control arms that will allow you to correct the driveshaft angle.

Furthermore, the shocks and struts must match the springs’ performance. High-quality performance shocks will ensure that your car maintains optimum contact with the road, which is critical for handling and ride comfort. When lowering your Mustang, it would be a good idea to consider upgrading your shocks and struts.

Maintaining Ride Comfort and Safety

While lowering your Mustang GT can enhance its performance, it’s vital to remember that these modifications can also affect ride comfort and safety. With lowering springs, your car will indeed have a stiffer ride, which some drivers might find uncomfortable.

To mitigate this, consider a set of springs that offer progressive rate springs. These springs are softer during normal driving conditions for comfort but stiffen under hard cornering to improve handling. Additionally, ensure the tires are well-balanced and the alignment is correct to prevent uneven tire wear.

Safety is another paramount concern. Ensure the modified setup doesn’t compromise the car’s braking ability. You want a setup that enhances your Mustang’s handling without putting you at undue risk.


In the quest to improve your Ford Mustang GT’s handling, lowering springs can provide significant benefits. However, it’s essential to approach the modification with a holistic view. Consider not just the springs, but how they interact with other components such as the suspension, tires, and brakes. Choose quality components and take into account your driving comfort and safety. With proper planning and execution, lowering springs can deliver a Mustang GT that’s a pleasure to drive, offering precise control and improved performance.

Synchronizing Lowering Springs with Shocks and Struts

One crucial consideration when installing lowering springs on your Ford Mustang GT is ensuring they work smoothly with the shocks struts. The shocks and struts play a significant role in your car’s suspension system, absorbing road irregularities and helping maintain tire contact with the ground. When you lower your car, it’s recommended to upgrade your shocks and struts to match the performance of the new springs.

For example, many Mustang owners and forum members rave about the benefits of pairing lowering springs with Koni yellows, high-performance shock absorbers known for their adjustable damping. The adjustable feature of the Koni yellows allows you to fine-tune your ride quality, providing a smooth ride under normal driving conditions, and firming up when you’re pushing the car to its limits.

Moreover, you should also consider integrating sway bars. These components help reduce body roll during sharp turns, further enhancing your car’s handling. A good rule of thumb is to match the front rear sway bars to the stiffness of your springs – stiffer springs require stiffer sway bars.

Lastly, don’t forget about installing adjustable control arms and camber bolts. The lowering springs will inevitably change the driveshaft angle and wheel alignment, which can lead to uneven tire wear and premature component failure if not rectified. Adjustable control arms and camber bolts allow you to correct these angles, ensuring optimal performance and longevity of your Mustang GT.

Important Considerations and Closing Thoughts

Before you start your journey towards improved handling with lowering springs, remember to consider your objectives and driving style. Are you looking to track your car, or is it mostly for street handling? These decisions will significantly influence the type of modifications you need.

If you frequent the track, a more aggressive setup may be appropriate. However, for daily driving, you need a balance between performance and ride comfort. In this case, forum members often recommend Eibach Pro springs for their perfect blend of comfort and performance.

Moreover, remember to consider essential safety components like the Panhard bar and bump stops. The Panhard bar helps maintain the lateral stability of the rear axle, while bump stops prevent the suspension from bottoming out during extreme conditions.

Finally, always have an experienced professional install these components. While you might be tempted to do it yourself, the installation requires expertise to ensure the components are correctly fitted and aligned, ensuring you’ll get the most out of your Mustang GT.


Lowering the suspension of your Ford Mustang GT can significantly improve its handling. It reduces body roll, improves aerodynamics, and gives your muscle car that aggressive stance. However, it’s not as simple as replacing the stock springs with lowering springs. It requires careful planning and a detailed understanding of how each component – from control arms to Koni yellows and sway bars – works together to deliver optimal performance.

Remember, no single modification is the silver bullet for improved performance. But with a holistic approach and quality components, your Mustang GT will indeed become a beast on the streets, providing you with the thrilling driving experience you crave. Whether you’re a thread starter in a forum or a seasoned Mustang gen, lowering springs can help you achieve a ride with an impressive blend of performance and comfort.
