How to Install an Adjustable Rear Wing on a Honda Civic for Autocross Events?

Autocross is a popular form of grassroots motorsport. Participants navigate through a course delineated by traffic cones, putting their driving skills to the ultimate test. While it may not be as high-speed as traditional track racing, the tight turns and quick maneuvers required mean that your car’s handling becomes paramount. One crucial modification for improving your vehicle’s performance in these situations is the installation of an adjustable rear wing.

If you’re a Honda Civic owner and autocross enthusiast, learning how to install an adjustable rear wing should be high on your to-do list. This article will guide you through this process, providing practical, easy-to-follow steps, while also explaining the benefits of this modification.

Choosing the Right Wing for Your Car

Choosing the right wing for your Honda Civic is a crucial first step in this process. While there are many wings available on the market, not all of them are suitable for autocross racing or specifically for a Civic.

When selecting a wing, consider its weight and the materials it is made of. A wing that weighs less than 15 lbs is ideal. It should be sturdy but light enough not to weigh down your vehicle. Commonly, wings are made out of aluminum or carbon fiber; both materials are lightweight yet robust.

Also, consider the wing’s adjustability. An adjustable wing allows you to alter the angle of attack, increasing or decreasing the downforce as necessary. This feature is particularly important in autocross, where the ability to adapt to different track conditions can drastically improve your lap time.

Removing the Stock Rear Wing

Before you can install the new adjustable wing, the stock rear wing on your Civic needs to be removed. Please note that this process may vary slightly depending on the model and year of your Civic.

Start by opening your car’s trunk. Locate and remove the plastic clips securing the trunk’s liner. Doing so will expose the mounting points for the stock rear wing. There should be four bolts securing the wing to the trunk. Using a ratchet and socket, remove these bolts carefully.

After removing the bolts, gently lift the rear wing away from the trunk. Be sure to keep the removed hardware in a safe place, as you may need it later.

Installing the Adjustable Rear Wing

Now that you’ve removed the stock rear wing, it’s time to install your new adjustable wing. Begin by aligning the mounting points of the wing with those on your car’s trunk. It’s essential to ensure that it’s centered to maintain the balance of your vehicle.

Once the wing is positioned correctly, secure it in place using the bolts you’ve received from the wing manufacturer. If these bolts aren’t compatible with your Civic’s mounting points, you may need to use the ones you removed earlier.

Next, tighten each bolt until the wing is firmly secure. It’s crucial that the wing doesn’t wobble or move around when the car is in motion, as this could impact its effectiveness and potentially damage your vehicle.

Fine-Tuning Your Wing for Optimal Performance

After you’ve installed your adjustable rear wing, you’ll need to fine-tune it to ensure optimal performance. By adjusting the wing’s angle, you will alter the level of downforce it produces.

In general, a steeper wing angle will create more downforce, improving traction and allowing for tighter turns. However, more downforce also means more drag, which can slow your car down on straightaways.

On the other hand, a flatter wing angle reduces downforce, allowing for higher speeds on straight sections of the track but reducing grip in corners.

For autocross events, where tight turns and quick maneuvers are the norm, a steeper angle is usually recommended. However, this will depend on your driving style and the specific track conditions. Experiment with different angles during your practice runs to find the ideal setting.

Maintaining Your Rear Wing

Once your rear wing is installed and adjusted, don’t forget about maintenance. Regular checks and adjustments are necessary, especially after each autocross event.

Inspect the wing and its mounting points for any signs of damage or wear. Loose bolts should be tightened, and any broken parts should be replaced immediately. Also, depending on the wing’s material, you may need to clean it regularly to keep it in good working order.

Each time you adjust the wing’s angle, make sure to test drive your car before hitting the track. Even small changes can significantly impact your vehicle’s handling, so it’s better to be safe than sorry.

Installing an adjustable rear wing on your Honda Civic can significantly improve your performance at autocross events. It’s a project that requires some effort, but the benefits you will reap in improved lap times and better handling make it a worthwhile investment.

Remember, safety should always be your primary concern. If you’re unsure about any part of the installation process, don’t hesitate to consult a professional for help.

Adjusting the Wing Mounts for Better Aerodynamics

Adjusting the wing mounts is an essential step after installing your adjustable rear wing. The position of the wing mounts can influence the aerodynamics of your Honda Civic, thus affecting its performance on the autocross track.

Before you begin adjusting, it’s important to understand the objective. The goal is to position the wing in a way that it directs air over the back of your car for increased downforce without causing excessive drag.

Start by adjusting the wing’s position in relation to the roofline. If it’s too low, it will not serve its purpose of directing the airflow. If it’s too high, it could cause unnecessary drag that slows your vehicle down. A sweet spot usually exists somewhere in-between, which you will need to determine through trial and error.

Next, consider the proximity of the wing to the rear of the car. The further back it is, the more leverage the downforce will have, thereby increasing its effectiveness. However, extending the wing too far back could make the car unstable, especially at high speeds.

Make sure the wing is level with your Honda Civic’s front bumper and rear. An uneven wing will not distribute downforce evenly, which could negatively affect the handling of your race car.

Remember, it’s your responsibility to make necessary adjustments to your wing mounts based on your driving style and track conditions. Always conduct test drives after any modifications to avoid any surprises on the race day.

Ensuring the Durability of Your Wing with High-Quality Materials

Longevity is a key factor to consider when installing an adjustable rear wing on your Honda Civic. Choosing a wing made from high-quality, durable materials like carbon fiber or aluminum can significantly extend its lifespan.

Carbon fiber is a popular choice due to its high strength-to-weight ratio. It’s light enough not to add unnecessary weight to your vehicle but strong enough to withstand the pressures of autocross racing. Showroom stock or custom-made carbon fiber wings are usually more expensive but promise excellent durability and performance.

Aluminum, on the other hand, is a more affordable option and still delivers a good performance. Ensure the aluminum is aircraft-grade to guarantee its strength and durability.

Regardless of the material you choose, ensure your wing is well-taken care of. Regularly inspect it for any damage or wear and replace any broken parts immediately. A well-maintained wing will not only last longer but will also perform better, helping you receive those much-desired likes, posts likes, and accolades from fellow autocross enthusiasts.


Installing an adjustable rear wing on your Honda Civic for autocross events isn’t just about enhancing the aesthetics of your race car. It’s about improving its aerodynamics, increasing downforce, and ultimately, boosting your performance on the track. Remember, the right wing and its correct installation and maintenance can make a significant difference in your autocross performance. Always stay vigilant about the conditions of the wing and make necessary adjustments or replacements when required. Safety is paramount, so if you’re ever unsure about anything, seek help from a professional.
