Coilovers vs. Springs


If you are a car enthusiast or someone looking to improve their vehicle’s suspension, you might have come across the terms “coilovers” and “springs.” Both are popular aftermarket suspension upgrades that can significantly impact your car’s performance and ride quality. In this article, we’ll explore the differences between coilovers and springs to help you make an informed decision based on your specific needs and preferences.

What Are Coilovers?


Coilovers are a type of suspension system that combines a coil spring and shock absorber into a single unit. Unlike conventional springs, which are separate from the shock absorbers, coilovers integrate both components into one assembly and there are various sizes available based on the vehicles such as coilover for 350z.

The Construction of Coilovers

The core components of coilovers include the coil spring, shock absorber, and a threaded shock body. The coil spring surrounds the shock absorber, providing the main support for the vehicle’s weight. The threaded shock body allows for height adjustment, giving drivers the ability to fine-tune their ride height.

Adjustability and Customization

One of the primary advantages of coilovers is their high level of adjustability. Enthusiasts can tailor their car’s ride height and suspension stiffness to suit their driving preferences and road conditions. Coilovers are especially popular among racing enthusiasts who require precise tuning for optimal performance on the track.

Performance Benefits of Coilovers

Coilovers offer several performance benefits, including improved handling, better weight distribution, and reduced body roll during cornering. The ability to adjust the suspension settings allows drivers to find the perfect balance between comfort and sportiness.

What Are Springs?


Springs, on the other hand, are a more traditional suspension upgrade. They consist of coil springs that are separate from the shock absorbers. While not as sophisticated as coilovers, springs can still provide significant improvements over stock suspension systems.

The Construction of Springs

Springs are essentially coiled wires made from various materials, such as steel or composite materials. They come in different spring rates, which determine how stiff or soft the suspension feels.

Limited Adjustability

Unlike coilovers, springs have limited adjustability. Once installed, the ride height and stiffness are generally fixed and cannot be easily altered. This lack of adjustability may limit customization options for some drivers.

Performance Benefits of Springs

Springs can improve a vehicle’s handling and stability by reducing body roll and improving weight distribution. They are often more affordable than coilovers, making them a popular choice for casual enthusiasts or daily drivers seeking a suspension upgrade.

Coilovers vs. Springs

When deciding between coilovers and springs, it’s essential to consider the following key differences:

Ride Height Adjustability

Coilovers excel in this aspect, as their threaded shock bodies allow for easy and precise adjustments to the ride height. Springs, on the other hand, have a fixed ride height, making them less suitable for drivers seeking dynamic changes in their vehicle’s appearance and performance.

Handling and Cornering

Due to their enhanced adjustability and integration of shock absorbers, coilovers offer superior handling and cornering performance. They provide a more responsive and controlled driving experience, especially during aggressive driving or on the racetrack. Springs, while still improving handling, might not match the precision of coilovers.

Comfort and Ride Quality

Springs tend to offer a more comfortable and forgiving ride, particularly when driving on rough or uneven roads. Coilovers can be stiff, especially when set to a sportier configuration, which may sacrifice some comfort for improved performance.

Factors to Consider When Choosing Between Coilovers and Springs

To determine whether coilovers or springs are the right choice for you, consider the following factors:

Budget and Cost

Coilovers are generally more expensive than springs due to their advanced design and adjustability. If you’re on a tight budget, springs might be the more suitable option, providing a noticeable improvement over stock suspension without breaking the bank.

Intended Use and Driving Style

Consider how you primarily use your vehicle. If you participate in track days or aggressive driving, coilovers’ performance advantages may be worth the investment. For daily drivers or casual enthusiasts, springs can provide a good balance of comfort and handling.

Skill Level and DIY Installation

Installing coilovers can be more complicated than springs, often requiring specialized tools and knowledge. If you’re a seasoned DIY enthusiast with mechanical expertise, this might not be an issue. However, if you’re unsure about installation, seeking professional help is crucial to avoid potential damage to your vehicle.

Maintenance and Longevity

Coilovers may require more frequent maintenance due to their adjustable components. Regular checks and lubrication are essential to keep them performing optimally. Springs, being simpler in design, typically have lower maintenance requirements and can last a long time with proper care.


Ultimately, the choice between coilovers and springs depends on your specific needs and preferences as a driver. Coilovers offer unparalleled adjustability and performance benefits, making them an excellent choice for enthusiasts seeking the utmost control over their suspension. On the other hand, springs provide a more budget-friendly option for casual drivers seeking a noticeable improvement in ride quality and handling.
