Coilovers vs Air Bag Suspension

Coilovers and air bags are two popular suspension upgrades. They not only transform your ride quality, but also change the way your car looks.

Choosing between the two may seem confusing at first, but as you learn more about how each upgrade works and what to expect from your car’s handling — it will make a lot more sense.

In this guide, we’ll take a deep look at air bags and coilovers along with the many benefits they offer to help you choose the right solution for your driving style.

Air Bags

As the name suggests, air bags are a lot like air balloons. Also known as “air ride” suspension, they’re a type of air suspension system that replaces your car’s OEM suspension, and their main goal is to support your car’s weight.

Air bags connect to an air compressor and an air reservoir. With the help of this compressor, air bags inflate which results in a raised car height. As for ride quality and handling, more air would mean a stiffer ride while less air would mean a soft ride.

By using either a control unit inside the car or a Bluetooth app, you can easily inflate or deflate the bags through the compressor, which lets you easily adjust the ride height without any hassle. When bags are deflated, your car lowers to the ground.

Pros

  • Easily adjustable ride height
  • Delivers a smooth ride
  • Can carry a heavy load

Cons

  • More expensive than other suspension modifications
  • They don’t last as long as coilovers or lowering springs
  • Few air ride kits can match the performance of coilovers

Coilovers

Coilovers are suspension components that prevent your car from scraping the road as you drive.

The mechanism is simple — a coiled spring surrounds the vehicle’s damper and both these components work together to absorb impact from the wheels — especially when your car goes over bumps in the road. Depending on the spring rate, you’ll either enjoy a stiff or a soft ride.

Aside from the performance benefits they offer, most drivers use them to raise or lower their cars.

Pros

  • Perfect for improving handling
  • More durable than air suspension systems
  • A wide range of adjustment, including height, compression, camber, caster and more

Cons

  • Often a stiffer ride
  • Ride height is “static”, meaning it cannot be adjusted by the flip of a switch
  • Adjusting ride height requires tools and removal of wheels

Air Bag Suspension vs Coilovers: An In-Depth Look

While air bags and coilovers serve a similar purpose, the difference lies in their mechanism and the ultimate handling applications they work best in.

One gives you more adjustability while the other offers more durability, precision, and resistance against wear and tear. Here’s an in-depth look at air suspension vs coilovers.

Aesthetics

Let’s be honest. If you’re installing airbags, it’s not just about the comfort, but also the incredibly slammed look that’s bound to turn heads. Who doesn’t like the way their car looks when lowered all the way to the ground after all?

If you’re a motorhead that frequents car events, air bags are perfect for that type of thing as they can literally be done with the push of a button.

Coilovers on the other hand, are much more work to raise and lower your car.

Improved Handling

If you’re looking to improve your car’s handling, coilovers are the way to go. They’re tuned to reduce a certain amount of body roll which makes them perfect if you want to drift, take them to a track day, or even take them out for a day of spirited driving.

For a daily driven car, air ride suspension can be quite practical and comfortable.

Air ride suspension, on the other hand, is more suitable for daily drivers. They enable your car to function smoothly and provide the driver a comfy ride.

Ride Quality

Ride quality is exactly where air bags really shine. Depending on the spring rate and how the shocks are valved, coilovers may seem harsher over bumps. Air bags seamlessly glide right over them and provide a smoother ride.

There’s also the fact that with air bags, you can adjust your car’s ride height anywhere, anytime — all at a press of a button.

With air bags, you can also add additional weight to your car without it bottoming out or feeling unbalanced. In fact, the raised car height will prevent the rear end of your car from sagging and consequently prevent tire wear and tear too.

Although you can put coilovers on a daily driver, it’s not going to be as comfortable as air bags. While coilovers can also help support an increased load, they’re mainly used to improve performance.

Track Use

Coilovers are predominantly used in motorsports due to their predictable behavior. When you’re driving at high speeds, you’re going to need exceptional handling and control while cornering — which is what coilovers do best.

There was a time that air bags were frequently used in NASCAR given their ability to bear heavy load without sacrificing balance or ride quality. But drivers soon switched to coilovers because they wanted the predictable and reliable performance that they offered.

Multi-rate springs provide a suspension setup that adjusts to handle various scenarios without you needing to physically adjust them. That’s because they’re custom wound to resist different amounts of compressive force. You just can’t expect air bags to perform the same way.

Another reason coilovers are great for track days is that they’re more durable than air bags. Since racetracks have uneven roads and changing surfaces, it could cause your air bags to rupture unexpectedly.

In addition to all of this, when comparing bags vs coilovers for track use, it’s obvious that coilovers allow you to customize several performance attributes of your suspension system such as rebound, damping, compression, and spring rate. All of those affect how your car feels on the track.

Air Ride or Coilovers: Purpose Matters

In the end, it all comes down to what you want out of your car’s handling and performance and where you plan to drive it. Your budget may also affect your choice especially when you see that air suspensions are significantly more expensive.

If you want a kit that’s going to improve your overall performance, choose coilovers. Whether you’re on the street or track, you’ll definitely notice the superior predictability and handling that they bring to the table.

But if you want a smoother ride, unmatched adjustability, and a slammed look — air suspension bags are the way to go. They’ll also handle more weight without making your car feel unbalanced.

Just don’t be surprised to find that air bags wear out quicker than coilovers, so maintaining or replacing them can become an expensive endeavor.
