Coilovers: What They Are and Why You Might Want One

If you’ve been looking at ways to make your ride sit lower and handle better, you’ve probably heard the term “coilovers.” In simple terms, a coilover is a shock absorber that comes with a built‑in spring. Unlike a stock suspension that has separate springs and shocks, coilovers let you adjust ride height and stiffness in one package.

Why do people swap stock shocks for coilovers? The main reasons are better grip, a more aggressive stance, and the ability to fine‑tune the car for daily driving or track days. With a coilover you can lower the car for a sleek look and still keep the comfort you need on the road.

How Coilovers Work

A coilover consists of a coil spring wrapped around a shock absorber. The spring handles the weight of the car, while the shock controls the bounce. Most coilovers have an adjuster ring that lets you raise or lower the car in small steps, usually a few millimetres at a time. Some also let you change the damping force, which changes how hard or soft the ride feels.

Because the spring and damper are together, you get a more consistent response than with separate parts. This consistency translates into steadier cornering, fewer body rolls, and a tighter feel when you brake. If you’ve ever felt your car sway too much in a corner, a good set of coilovers can cut that motion down dramatically.

Choosing the Right Coilover Set

Not all coilovers are created equal. The first question to ask is what you want the car to do. If you’re planning track days, look for fully adjustable coilovers that let you dial in both ride height and damping. For a street‑only build, a set with fixed damping but adjustable height might be cheaper and still give the lowered look you want.

Consider the spring rate too. A stiffer spring improves handling but can make the ride harsh on rough roads. A softer spring keeps comfort but won’t give the same level of performance. Many manufacturers offer a range of spring rates, so you can pick one that matches your driving style.

Brand reputation matters as well. Companies that specialize in performance suspension often provide better build quality and longer warranties. Look for reviews from other owners who have installed the same model on a similar car.

Finally, think about cost. Coilovers can run from a few hundred pounds to over a thousand. Remember to add the price of installation and any required alignment. A professional shop will usually need a few hours to fit the units and set them up correctly.

Once you’ve chosen a set, the installation is the next step. Most car owners prefer to have a professional do the work because it involves removing the wheels, unbolting the existing suspension, and fitting new mounting points. If you’re handy, you can DIY, but you’ll need a solid jack, torque wrench, and a willingness to spend a couple of hours on the job.

After installation, get a proper wheel alignment. Changing ride height affects camber, toe, and caster, which in turn influences tire wear and handling. An alignment will ensure the car tracks straight and the tires last longer.

Maintenance is straightforward: check the coilover nuts for tightness every few months, look for oil leaks around the shock, and keep an eye on any unusual noises. Some coilovers have interchangeable springs, so you can upgrade later without swapping the whole unit.

In short, coilovers give you the power to shape how your car looks and feels. By understanding how they work, picking the right set for your needs, and installing them correctly, you’ll get a lower stance, sharper handling, and a more enjoyable drive. Ready to give your car the upgrade it deserves?
