Suspension Upgrade Guide – Coilovers vs Lowering Springs

When it comes to upgrading a vehicle’s suspension, enthusiasts and performance drivers often find themselves at a crossroads, choosing between coilovers and lowering springs. Both options offer distinct advantages and cater to different needs and preferences. This guide aims to delve into the nuances of coilovers and lowering springs, helping you make an informed decision for your suspension upgrade.

Understanding the Basics

Before comparing coilovers and lowering springs, it’s essential to grasp their basic functions within a vehicle’s suspension system. The suspension system’s primary role is to provide a smooth ride by absorbing and dampening road shocks, while also maintaining tire contact with the road for steering stability and braking efficiency.


Coilovers, short for “coil spring over shock,” are integrated assemblies that replace the entire stock spring and shock absorber setup with an adjustable spring and shock unit. They offer a wide range of adjustability, including ride height, spring preload, and in many cases, damping characteristics (how quickly the shock absorbers compress and rebound). This adjustability allows drivers to fine-tune their vehicle’s handling and stance to their exact preferences and driving conditions.

Key Features of Coilovers

Adjustable Ride Height

One of the most appealing features of coilovers is their ability to adjust the ride height of a vehicle. This adjustability allows for a lower stance, which not only improves the vehicle’s aesthetics but also enhances its aerodynamics and lowers its center of gravity, leading to improved handling and stability.

Spring Preload Adjustment

Coilovers offer the capability to adjust spring preload, which is the amount of tension applied to the spring before it is compressed by the weight of the vehicle. Adjusting the preload can alter the suspension’s responsiveness and handling characteristics, allowing drivers to tailor the vehicle’s performance to their liking.

Damping Adjustability

Many coilover systems come with adjustable damping, which controls the rate at which the shock absorbers compress and rebound. This feature enables drivers to fine-tune the balance between ride comfort and handling performance, making coilovers versatile for both daily driving and track use.

Lowering Springs

Lowering springs are designed to replace only the stock springs, using the original shock absorbers. They are primarily used to lower the vehicle’s ride height, which can improve handling by lowering the center of gravity. However, lowering springs offer limited adjustability compared to coilovers, mainly affecting ride height and, indirectly, the vehicle’s handling characteristics.

Key Features of Lowering Springs

Reduced Ride Height

The primary function of lowering springs is to decrease the vehicle’s ride height, which directly influences the car’s appearance and handling dynamics. A lower center of gravity helps in reducing body roll during cornering, enhancing the vehicle’s stability and responsiveness.

Compatibility with Stock Shock Absorbers

Lowering springs are designed to work with the vehicle’s original shock absorbers, making them a more straightforward and less invasive upgrade than coilovers. This compatibility ensures that the upgrade process is not only more accessible but also more cost-effective.

Improved Aesthetics

Beyond performance enhancements, lowering springs significantly improve a vehicle’s visual appeal. The reduced gap between the tires and wheel wells offers a more aggressive and sporty look, appealing to many car enthusiasts.

Coilovers vs Lowering Springs: A Detailed Comparison


Coilovers are the go-to choice for drivers seeking maximum performance and adjustability. The ability to adjust ride height, damping, and sometimes even spring rate allows for precise handling tuning. This makes coilovers ideal for track days, racing, or spirited street driving where handling characteristics need to be finely tuned to match driving conditions or personal preferences.

Lowering Springs, while improving handling by lowering the vehicle’s center of gravity, do not offer the same level of adjustability. The fixed spring rate and height reduction can improve cornering performance and reduce body roll, but may not be as optimized for performance driving as coilovers.


Coilovers can be adjusted for a softer or firmer ride, but the range of comfort is generally skewed towards performance, meaning a firmer ride. High-quality coilovers are designed to offer a balance between performance and comfort, but the emphasis is on handling improvements.

Lowering Springs tend to offer a ride that’s closer to stock in terms of comfort, albeit slightly firmer due to the reduced suspension travel and stiffer spring rates. For daily drivers, this can be a more practical option, providing a good balance between improved aesthetics and handling without sacrificing too much comfort.


Coilovers are typically more expensive than lowering springs due to their complexity and adjustability features. The investment is justified for those who demand the utmost in performance tuning and customization.

Lowering Springs are a more budget-friendly option for those looking to lower their vehicle and achieve a sportier look without a significant investment. While they offer less adjustability, they can still provide a noticeable improvement in handling and aesthetics.

Installation and Maintenance

Coilovers require a more involved installation process, often necessitating professional installation and alignment to ensure optimal performance and safety. They also require regular maintenance and adjustments to maintain their performance benefits.

Lowering Springs are simpler to install and can often be done by enthusiasts with some mechanical knowledge. They require less maintenance than coilovers, making them a more set-and-forget option for those not looking to constantly tweak their setup.


In conclusion, the choice between coilovers and lowering springs for your vehicle’s suspension upgrade is a decision that hinges on a balance of performance, comfort, cost, and personal preference. Coilovers stand out as the premier option for those seeking the utmost in adjustability and performance tuning. They cater to the dedicated enthusiast or racer who demands precise control over their vehicle’s handling and stance, albeit at a higher cost and with more maintenance requirements. On the other hand, lowering springs offer a more accessible entry point into suspension modifications, providing a noticeable improvement in aesthetics and handling with a simpler installation process and less impact on ride comfort.

Ultimately, your decision should be guided by how you intend to use your vehicle, your budget, and your willingness to engage in ongoing maintenance and adjustments. Whether you prioritize the track-ready adjustability of coilovers or the straightforward, cost-effective enhancement provided by lowering springs, both options present viable paths to achieving a more responsive and visually appealing ride. By carefully considering your needs and the unique characteristics of each suspension upgrade option, you can ensure a satisfying improvement to your vehicle’s performance and aesthetics.
