What is a Coilover Kit?
Coilover kits are the most popular type of suspension system. They’re made to lower your vehicle and improve handling. The term “coilover” is short for “coil over shock” — which is a suspicion system where the coiled springs go over the shock absorber.
Suspension springs are made into coils because that shape allows for easy compression and retraction. Coilovers refer these to these coiled springs which go over the shocks.
A coilover combines the vehicle’s shock absorber and coil spring. This connects the vehicle’s body to the wheels. Coilovers allow precise adjustments to both the spring height and the firmness of the shocks.

Frequently Asked Questions about Coilover Kits
How Do Suspension Systems Work?
To best understand the benefits of a coilover kit, let’s first take a look at how suspension systems work. Your suspension system controls your tire’s contact with the road. The point of upgrading your suspension is to lower your vehicle, which increases that contact.
Shop for a suspension system like you’re Goldilocks shopping for a bed. If your vehicle’s suspension is too soft, traction and performance will be negatively affected. This is because the tires will have reduced contact with the road during cornering due to weight transitions.
However, a suspension system which is too hard will cause problems, too. If the suspension is too stiff, the car can slide out of your control. A stiff suspension prevents the tire from making the proper amount of contact with the road.
Coilover kits are adjustable, which helps prevent these problems. The car can be lowered to the desired height without causing the suspension to be too soft or stiff.
How Low Can My Car Go?
Specifics will vary based on the type of coilover you use and the type of vehicle you have. Most coilovers will lower the vehicle about half an inch even at the highest setting. However, you’ll probably be able to lower the vehicle another three to four inches if you like.
Most cars can only be lowered two inches before driving issues start to occur. However, sometimes cars are lowed beyond normal drivability for displays or car shows.
Additionally, some coilovers will actually raise your vehicle. These will clearly be labeled as off-road coilovers. They’re typically used for rally cross, Baja racing, four-wheeling and similar activities.
Can I Lower the Springs to Lower My Car?
You can, although it’s not usually the best option. Basically, you can simply replace your existing stock springs with replacements which are anywhere from a half inch to two-and-half inches shorter. Typically, you’ll also want to replace stock shocks with high-performance ones, or else the new springs can make the ride pretty rocky.
Adding shorter springs will lower your ride. But the height won’t be adjustable, handling can be pretty stiff and the cost can be high.
What are Full Bodies Coilovers?
This refers to a complete kit which includes shocks. Might also contain top mounts. The main benefit here is completeness. The shocks are specifically designed to handle the demands of the lowered car, which will have higher spring rates. On the downside, these complete sets are the most expensive option.
What are Sleeve Coilovers?
These coilovers don’t include shocks, which does lower their price pretty substantially. While they will lower your car, there are some drawbacks. Most stock shocks aren’t always designed to work on lowered vehicles. Adding coilovers without upgrading your shocks typically only results in limited improvements to handling.
However, sleeve coilovers can work great with a select few types of vehicles. The Mitsubishi Lancer EVO, Subaru WRX STi and certain other vehicles have factory-installed performance stocks. These shocks will normally work well with sleeve coilovers to improve handling for lowered cars.
Can I Install Coilover Kits Myself?
Possibly. If you’re comfortable working on your own car, installing a coilover is usually a job you can handle yourself. However, know that it’s time-consuming and can be a lot of work. You’ll need to remove all the tires and lift the car up.
Plus, if you’re installing a kit, you’ll need to install not just the coilovers but also the shocks. While installation isn’t terribly difficult, adjusting the various settings such as the height and firmness of the shocks does require some technical understanding. As discussed above, shocks which are too soft or too firm can affect car control and performance.
Additionally, calibrating your coilovers will typically require some test runs. You’ll want to cover different types of terrain and compare how the shocks feel. Testing should also cover the springs. Generally, springs should be as light as possible while remaining strong enough to support the vehicle.
The bottom line is you can install coilovers yourself if you’re comfortable working with cars, especially working around the suspension system. However, if you’re new to coilovers, you’ll get far better results with professional installation.
Excited to add a coilover kit to your car? Improved handling and responsiveness can be yours, whether you’re racing at a track or just want better performance on your daily drive. Plus, the best coilovers allow you to adjust the height of your vehicle without putting unnecessary strain on your shocks. Overall, coilover kits are more than just useful – they’re also a fun way to increase the cool factor of any car!
