When it comes to improving your car’s performance, handling, and appearance, few modifications offer as much benefit as installing a set of coilovers. Coilovers are a popular choice for car enthusiasts, offering superior adjustability, comfort, and performance. Whether you're looking to improve your car's handling on the track, lower your car for a sportier look, or get the perfect suspension setup for daily driving, coilovers are the key to unlocking your vehicle's potential.
In this comprehensive guide, we will walk you through everything you need to know about coilovers—what they are, how they work, the different types available, the benefits they offer, and how to choose the best coilovers for your car.
1. What Are Coilovers?
Coilovers are a type of suspension system that combines a shock absorber (dampers) and a coil spring into one unit. This all-in-one design allows for adjustable ride height, spring rates, and damping forces, making them a versatile option for performance enthusiasts. Unlike traditional suspension setups, coilovers allow for fine-tuning of your car’s handling characteristics, providing greater control and adaptability to different driving conditions.
Key Features of Coilovers:
- Adjustable Ride Height: You can adjust the height of your car to achieve a lower center of gravity or improve aerodynamics.
- Adjustable Damping: Coilovers allow you to fine-tune the shock absorber’s damping settings for more control over the suspension stiffness.
- Versatile Performance: Ideal for street driving, track racing, and motorsports.
2. How Do Coilovers Work?
Coilovers work by providing a combination of spring compression and shock absorption. The coil spring is responsible for supporting the car's weight and absorbing impacts from the road, while the shock absorber controls the rate at which the suspension compresses and rebounds. Together, these components control how the car handles bumps, dips, and corners, and they help maintain the vehicle’s stability.
Components of a Coilover:
- Spring: Provides the primary suspension support and absorbs impacts.
- Shock Absorber: Dampens the spring's movement and controls how quickly the suspension compresses and rebounds.
- Adjuster Knob: Allows the user to adjust the ride height, damping force, and in some cases, spring rates.
3. Types of Coilovers: Which One Is Right for You?
There are several different types of coilovers available, each offering unique features and performance characteristics. Choosing the right type depends on how you plan to use your car and the level of adjustability you need.
1. Street Coilovers:
- Best For: Daily driving and street performance.
- Features: Adjustable ride height and moderate damping control for a balance between comfort and performance.
- Example Brands: BC Racing, Ksport, KW Variant 1
2. Track Coilovers:
- Best For: Track days, autocross, and motorsports.
- Features: More aggressive spring rates and damping adjustments. These are designed for maximum performance and handling on the track but may be less comfortable for daily driving.
- Example Brands: Ohlins, Tein, HKS
3. Drift Coilovers:
- Best For: Drifting and motorsports requiring heavy suspension adjustments.
- Features: Higher rebound and compression adjustments to allow for precise control during high-speed maneuvers.
- Example Brands: SLRspeed
4. Air Coilovers (Air Suspension):
- Best For: Those who want adjustable ride height with the ability to "air out" the suspension for show cars.
- Features: Offers adjustable height through an air compressor, providing a unique look and ride comfort.
4. Benefits of Installing Coilovers
Coilovers offer several benefits over traditional suspension systems. Here are some of the key advantages:
1. Improved Handling and Performance:
Coilovers allow you to fine-tune your car’s suspension to match your driving style. Whether you’re on a race track or driving on the street, you can adjust the suspension to maximize grip and stability.
2. Adjustable Ride Height:
One of the most appealing features of coilovers is the ability to adjust your ride height. Lowering your car can improve its handling by lowering the center of gravity, enhancing cornering ability and reducing body roll.
3. Customizable Comfort:
With adjustable damping, coilovers allow you to modify your suspension for comfort or performance. If you want a softer ride for daily driving or a stiffer setup for track performance, coilovers can deliver it.
4. Aesthetics:
Lowering your car can give it a more aggressive stance, improving its overall appearance. Many car enthusiasts install coilovers not just for performance benefits, but also for the visual appeal of a lowered car.
5. How to Choose the Best Coilovers for Your Car
Choosing the best coilovers depends on several factors, including your driving goals, budget, and the type of car you own. Here are some key things to consider:
1. Driving Style and Goals:
- Street Performance: Opt for coilovers with adjustable damping that can offer a balance between comfort and performance.
- Track/Competition: Look for coilovers with higher spring rates, more precise adjustments, and better overall durability.
- Daily Driving vs. Motorsports: If you're using the car primarily for daily driving, you might want something with a more comfortable ride. For motorsports, you’ll need a firmer, track-oriented setup.
2. Brand and Quality:
High-quality coilovers come from reputable brands like BC Racing, KW, Ohlins, and Tein. These brands offer durable, performance-oriented coilovers that are backed by years of research and development.
3. Budget:
Coilovers can range from budget-friendly options to high-end racing coilovers. Be mindful of your budget while considering factors like adjustability, build quality, and overall value for money.
6. How to Install Coilovers: A Step-by-Step Guide
While installing coilovers can be a bit technical, it is possible to install them yourself if you have the right tools and knowledge. Here’s a general guide on how to install coilovers on your car:
- Lift the Car: Use a jack to lift the car, and ensure it's securely supported by jack stands.
- Remove the Old Suspension: Remove the factory shock absorbers and springs.
- Install the Coilovers: Position the new coilovers in place, ensuring that they’re secured properly.
- Adjust Ride Height: Set the ride height to your desired level and tighten all bolts.
- Set Damping: Adjust the damping to your preferred setting for the best performance or comfort.
- Test Drive: Take your car for a test drive to ensure everything is functioning correctly.
7. Maintenance and Care of Coilovers
Proper maintenance is crucial to ensure that your coilovers perform optimally and last a long time.
- Regular Cleaning: Keep your coilovers clean from dirt, grime, and salt to prevent corrosion.
- Inspect the Springs and Shocks: Check for signs of wear, such as oil leaks or broken springs.
- Re-Valving: Over time, the shock absorber’s valving may wear out. Re-valving helps restore performance.
- Lubrication: Ensure that moving parts, such as adjusters and mounts, are adequately lubricated.
8. Coilovers vs. Springs and Shocks: Which is Better?
While springs and shocks may seem like a more budget-friendly option, coilovers offer superior adjustability and performance. Springs and shocks are typically a fixed setup, meaning you have limited options to customize your ride. Coilovers, on the other hand, offer greater flexibility and the ability to adjust both ride height and damping force.
9. Frequently Asked Questions (FAQ)

How long do coilovers last?
With proper maintenance, coilovers can last several years, with most high-quality coilovers lasting 3-5 years or more before requiring service.
Conclusion:
Coilovers are an essential upgrade for anyone looking to enhance their car's handling, performance, and aesthetics. By understanding the types of coilovers, their benefits, and how to choose and install them, you can take full advantage of this powerful modification.
