Everything About Car Coilovers

What is a coilover?

A car coilover is a suspension system component that combines a shock absorber and a coil spring into a single unit. The name “coilover” comes from the combination of “coil” spring and “over” the shock absorber.

The coilover unit replaces the stock suspension system on a car, and can be adjusted to alter the ride height and stiffness of the suspension. Coilovers are commonly used in high-performance vehicles, as they offer greater control and handling compared to stock suspension systems.

The shock absorber portion of a coilover is responsible for controlling the compression and rebound of the suspension, while the coil spring provides support and absorbs impact. The height of the coilover can be adjusted by threading the shock absorber body up or down within the coil spring, and the stiffness of the suspension can be adjusted by changing the tension of the spring.

Coilovers are available in a range of configurations to suit different driving styles and purposes, from street use to track racing. They can be expensive, but can significantly improve the handling and performance of a vehicle.

Why use custom coilovers on your car?

There are several reasons why someone might want to change the suspension on their car:

1. Improved handling and performance

Coilovers can improve the handling and performance of a vehicle by providing better control and responsiveness. This can be especially beneficial for high-performance cars that are driven on the track or for enthusiasts who enjoy spirited driving on the road.

2. Adjustable ride height

Coilovers allow for the ride height of a vehicle to be adjusted, which can improve the appearance and aerodynamics of the car. Lowering the ride height can also lower the center of gravity, which can improve handling and reduce body roll.

3. Customization

Coilovers come in a variety of configurations and can be customized to suit a driver’s preferences. This includes adjusting the stiffness of the suspension, as well as other features like rebound and compression damping.

4. Damaged or worn-out stock suspension

If the stock suspension on a car is damaged or worn-out, replacing it with coilovers can be a cost-effective solution. Coilovers are generally more durable and provide better performance than stock suspension systems.

5. Suspension upgrades

Coilovers can be part of a larger suspension upgrade, which may include other components like sway bars, control arms, and bushings. This can result in a significant improvement in overall handling and performance.

How to find quality car coilovers?

1. Compatibility

Make sure the coilovers are designed to fit your specific make and model of car. Coilovers that are not compatible with your vehicle may not provide the proper fit or performance. SCALE Suspension makes it easy to find the coilovers compatible with your vehicle. In doubt, you can always contact our skilled sales team.

2. Brand Reputation

Look for coilovers from reputable brands that have a history of producing quality suspension components. Read reviews from other drivers and do research on the brand’s reputation. SCALE has a long history of satisfied customer and high quality products that speak for themselves.

3. Build Quality

Check the materials used in the construction of the coilovers. Quality coilovers should be made from durable materials that can withstand the demands of high-performance driving.

4. Adjustability

Look for coilovers that offer a range of adjustability, including ride height and stiffness. The ability to fine-tune the suspension can improve performance and handling. At SCALE, our many options and configurations will ensure you can have the adjustability that you need.

5. Warranty

Check the warranty offered by the manufacturer. A quality coilover should come with a warranty that provides protection against defects and premature failure. SCALE offers a solid warranty with all purchases. You can buy with confidence!

6. Price

While price should not be the only factor to consider, it can be an indicator of quality. Be wary of very low-priced coilovers, as they may be of lower quality and not perform as well as more expensive options. We are very active to monitor low-quality dupes of SCALE products, and we encourage you to be vigilent as well. High quality coilovers require high quality material and good engineering, which cannot be found on mass-produced cheap coilovers.


Overall, it’s important to do your research and choose a quality set of coilovers that are compatible with your vehicle and provide the performance and adjustability you need.
