Common Suspension Issues in an EP3

Before upgrading your EP3's suspension, it's essential to identify and address any underlying issues that may compromise its stability and grip.

One familiar issue owners encounter is excessive body roll during cornering, which can significantly affect the vehicle's handling.

This problem can be mitigated by installing sway bars, commonly known as anti-roll bars and upgrading the suspension components that support the chassis, such as the bushings and control arms.

Another issue affecting your EP3's handling is a lack of responsiveness, often caused by worn-out shocks and struts.

These components are crucial in maintaining the vehicle's stability and absorbing road shock. Over time, they can become worn and lose effectiveness, leading to a sluggish response and poor handling.

Upgrading to high-performance shocks, struts, or coilover setup can significantly improve the EP3's responsiveness and overall driving experience.

Addressing these issues and upgrading your EP3's suspension can significantly enhance its handling and performance.

However, following a step-by-step process is essential to ensure everything is done correctly and safely.

This includes selecting the right components, installing them properly, and testing the vehicle's new suspension to ensure it meets your expectations.

Step 1: Assessing Your Current Suspension Setup

If you're considering upgrading the suspension on your Honda Civic EP3, evaluating your current setup is a crucial first step.

Start by thoroughly inspecting the condition of all your suspension components, paying close attention to any signs of wear and tear, such as leaking shocks, cracked springs, or excessive play in the bushings.

Additionally, take note of your vehicle's current ride height and handling characteristics.

Does it feel too soft and bouncy, prone to body roll during turns, or stiff and uncomfortable on rough roads?

Understanding these aspects of your EP3's current setup will help you make informed decisions when selecting the right upgrades for your suspension.

Step 2: Upgrading Your Shocks and Struts

The suspension of your EP3 is an essential component that is crucial in ensuring a smooth and comfortable ride. It is mainly controlled by the shocks and struts, which absorb the shock and vibrations caused by bumps and uneven surfaces.

However, consider investing in high-performance shocks and struts if you want to upgrade your car's performance and stability.

These upgraded shocks and struts will significantly enhance your car's ability to absorb bumps and maintain stability, especially during aggressive driving.

When selecting the correct shocks and struts, various factors exist, such as adjustability, damping characteristics, and overall performance.

These factors will help you choose the right shocks and struts to suit your driving style and needs. For EP3 owners, coilovers are an excellent option to consider.

They are highly adaptable and allow you to fine-tune your car's suspension to suit various driving conditions. You can adjust your suspension for daily driving, racing, or off-roading.

With coilovers, you can easily change the vehicle height, spring rate, and damping settings to perfectly balance comfort, performance, and stability.

Corner Weighting

Some coilovers feature an adjustable lower spring platform, which enables the car to be configured for corner weighting, resulting in balanced weight distribution and optimal tire performance.

This means that both front and rear tires on each axle need to bear equal weight for the car to operate efficiently during cornering, enhancing grip, increasing cornering speed, and decreasing lap times if on track.

Additionally, optional assister springs can be obtained to calibrate wheel droop to suit individual requirements.

Vehicle Height

In most cases, the height of a vehicle is determined by the position of the coilover bottom mount. However, this can vary depending on the manufacturer.

The damper body support can be adjusted up and down for various customisable height options. Occasionally, there may also be a spring platform to adjust.

If the adjustable bottom mount determines the vehicle height, the damper travel remains unaffected regardless of the ride height.

Damping Adjustment

In this example, we will explore BC-Racing BR coilovers. These coilovers boast a 30-way damping adjustment that combines rebound and compression in one adjuster, making them easy to use.

With this feature, you can fine-tune your vehicle to match the specific conditions you encounter. Adjusting the front and rear damping can modify how your car handles.

For example, if you increase the damping force on the rear relative to the front, the vehicle will move into a more oversteer-orientated stance. You can adjust your shocks' damping force or rate when compressing or rebounding.

Stiffer shock rates slow spring movements, while softer rates allow faster movement. If your shocks are too rigid, the tire contact patch may bounce off the road surface over bumps, causing unpredictable handling.

In this case, you should soften your shocks. However, if your shocks are too soft, the body of your car may bounce after hitting a bump or rut.

Finding the right balance between comfort and performance is essential, but it can sometimes be complicated. You must take baseline measurements and conduct incremental tests to achieve the desired results.

Camber Adjustment

In the automotive market, some coilovers come equipped with camber adjustable top plates. These top plates facilitate easy camber adjustments while driving.

Camber is a crucial element that helps distribute your vehicle's weight uniformly across the tire surface. If the camber is improperly set, it can lead to uneven tire wear, and your car may pull towards the side with the highest positive camber.

Therefore, setting up your camber correctly is essential to ensure that you always have optimal road contact, providing the best possible grip.

Maintaining proper camber gives you a more comfortable and safe driving experience.

Step 3: Installing Performance Springs

If you have decided to upgrade the shocks and struts rather than use coilovers on your EP3, consider installing performance lowering springs to optimise your car's handling.

These springs determine the suspension's stiffness and ride height, significantly affecting the car's overall performance.

Lowering springs are incredibly popular among EP3 owners because they improve the car's appearance and lower the centre of gravity, enhancing stability and reducing body roll.

Choosing springs designed explicitly for your EP3 is crucial to ensure proper fitment and compatibility.

One of the most popular options is the Ep3 Tein S.Tech lowering springs. These springs provide a 1.5 inch/40mm drop for a more aggressive appearance and improved road-holding capability.

The springs are designed to be used with OEM or replacement shocks, ensuring optimal performance and comfort.

Additionally, they are tested on North American roads to guarantee their reliability. Tein S.Tech lowering springs come with a 1-year limited warranty, and the spring length is guaranteed not to sag more than 5mm.

They are an excellent investment for those looking to improve their car's handling and appearance without compromising comfort or safety.

Step 4: Upgrading Your Sway Bars

The suspension system of the EP3 model heavily relies on sway bars, also referred to as anti-roll bars. The primary function of these bars is to minimise body roll while the vehicle is cornering.

If you want to enhance your EP3's cornering ability, upgrading to stiffer sway bars is viable.

However, it's crucial to strike a balance between stiffness and comfort. For instance, if you install sway bars that are too stiff, you risk negatively affecting the ride quality, particularly on uneven roads.

When selecting the level of stiffness for your sway bars, it's essential to consider your driving style and the type of roads you frequently drive on.

For instance, opt for stiffer sway bars if you're more inclined to aggressive driving.

On the other hand, if your focus is on comfort, you might prefer less rigid sway bars. One option worth considering is the Tegiwa anti-roll bar product line.

These bars are thicker than the stock bars and have multiple drop link mounting points for adjustability.

This feature lets you fine-tune the sway bar's stiffness level to match your driving style and road conditions. Upgrading the sway bars is straightforward and involves removing the old bar.

It's worth noting that the UK spec has a 19mm anti-roll bar, while the JDM has a 22mm bar.

Therefore, if you're upgrading from the stock sway bars, consider the compatibility of the new sway bars with your vehicle's specifications.

Step 5: Upgrading Your Bushings

Regarding your EP3's suspension system, it is essential to note that the condition of the bushings plays a crucial role in its overall performance.

Over time, these components can become less effective, leading to increased play and reduced handling precision.

We highly recommend upgrading to polyurethane or aftermarket bushings to address this issue.

Doing so can significantly improve your car's handling by lowering unwanted movement and maintaining proper alignment.

These bushings are durable and resistant to deformation, ensuring that your suspension components stay in place even during aggressive driving.
