Side skirts are one of the most popular aftermarket modifications among car enthusiasts, and for good reason. These seemingly simple additions can transform your vehicle’s aesthetics and play a pivotal role in enhancing its aerodynamic performance. Whether you’re a first-time modifier or a seasoned DIYer, understanding how to install side skirts correctly is essential to reap all their benefits-from improved stability and fuel efficiency to a sleek, aggressive look that turns heads on the street.In this comprehensive guide, we will walk you through everything you need to know about side skirts: what they are, the benefits they bring, the materials used, and a detailed, step-by-step installation process. We’ll also cover common challenges, maintenance tips, and even explore future trends in aerodynamic car modifications. Plus, we’ve included a beginner-friendly checklist and interactive elements to make your installation journey as smooth and rewarding as possible.
Side skirts, also known as rocker panels or side splitters, are aerodynamic components attached along the lower sides of your vehicle’s body, between the front and rear wheels. While they undeniably improve your car’s visual appeal by giving it a lower, more aggressive stance, their benefits extend well beyond aesthetics.
By minimizing the airflow underneath the vehicle, side skirts reduce lift and turbulence, which can otherwise destabilize the car at high speeds.
The reduction in underbody airflow increases downforce, improving traction and handling, particularly on curves and at highway speeds.
A study conducted by a prominent motorsport team demonstrated that installing well-designed side skirts reduced the drag coefficient of their test car by 5%, resulting in improved cornering stability and a measurable increase in fuel efficiency over a race distance.
To make an informed choice, it’s important to understand what side skirts are made from, their different types, and how these factors influence their performance and durability.
Side skirts are elongated panels that attach just below the doors and along the rocker panels of a car. Their purpose is to disrupt airflow underneath the vehicle, reducing air pressure beneath the chassis which contributes to lift.
Downforce: The downward pressure created by aerodynamic components that helps keep the car glued to the road.
Drag Coefficient (Cd): A numerical measure of how much resistance a car faces as it moves through the air.
Rocker Panel: The section of the car body between the wheel wells, underneath the doors.
Side skirts vary in shape, design, and materials. Choosing the right type depends on your goals, budget, and vehicle model.
Material | ✅Pro | ✅Cons |
ABS Plastic | Affordable, flexible, resistant to minor impacts | Less durable under severe conditions |
Carbon Fiber | Extremely lightweight and strong; premium look | High cost; requires careful handling |
Fiberglass | Customizable shapes; lightweigh | Brittle, prone to cracking |
Polyurethane | High impact resistance; flexible | Heavier than carbon fiber |
OEM Style: Factory-style skirts that maintain a subtle, clean look.
Aftermarket Aggressive: Larger, more pronounced skirts for a race-inspired appearance.
Universal Fit: Adjustable skirts that can be trimmed to fit various models.
Side skirts help channel airflow to reduce lift and drag, which increases high-speed stability.
Studies show improved aerodynamic flow can save up to 3-5% in fuel consumption under certain driving conditions.
Side skirts act as a shield, reducing stone chips and scratches to the rocker panels and lower body.
Before starting the installation, gather all necessary tools and materials. Preparation is critical to avoid mistakes and ensure a seamless process.
Side Skirts (model-specific or universal fit)
Drill and Drill Bits: Preferably variable speed with bits suitable for metal/plastic.
Screws and Fasteners: Self-tapping screws recommended for a secure hold.
Heavy-Duty Double-Sided Tape: For additional adhesion, particularly on curved surfaces.
Measuring Tape and Masking Tape: For precise marking.
Adhesion Promoter: To enhance tape bonding on painted surfaces.
Safety Gear: Gloves, goggles, and protective clothing.
Cleaning Supplies: Mild detergent, isopropyl alcohol, microfiber cloths.
Clean the Installation Area Thoroughly: Use mild detergent followed by isopropyl alcohol to remove oils and dirt, ensuring good tape adhesion.
Dry Completely: Moisture under the skirts can cause tape failure.
Mark Reference Points: Use masking tape to mark key attachment points and to guide positioning.
Work Environment: Install in a shaded or indoor area to avoid extreme heat or cold, which affects adhesive performance.
Follow these detailed steps carefully to achieve a professional-grade installation.
Align the skirts along the rocker panel.
Check for gaps or misalignment.
Use masking tape to temporarily hold them and note adjustments.
Inspect from multiple angles, including ground level and eye level.
With skirts held in place, mark drill points clearly with a pencil or marker.
Verify symmetry by measuring distances from front and rear wheel arches.
Use a center punch to avoid drill bit slipping.
Drill pilot holes carefully, avoiding wiring or fuel lines.
Clean surfaces again before applying double-sided tape.
Apply adhesion promoter if recommended.
Affix tape firmly to skirt edges.
Peel back tape liner in sections as you press skirts firmly into place.
Insert screws into drilled holes, tightening evenly but not over-tightening.
Check for any gaps or misalignment, adjusting as needed.
Confirm skirts sit flush against vehicle.
Use a level to ensure straightness.
Adjust screw tightness or tape positioning as needed.
Clean any fingerprints or smudges from installation.
Installation may not always go perfectly. Here are common issues and solutions:
Misalignment: Loosen screws, reposition skirts, and retighten.
Adhesive Failures: Reclean surfaces, apply primer, replace tape if needed.
Warping: Warm skirts gently with heat gun before installation to improve pliability.
Stripped Screws: Use slightly larger screws or rivets.
Proper maintenance is key to preserving both the appearance and function of your side skirts. Regular care extends their lifespan and keeps your car looking sharp.
Use a mild detergent and a soft microfiber cloth to clean the skirts regularly.
Avoid abrasive cleaners or stiff brushes that may scratch the surface.
Pay special attention to lower edges where road grime and salt accumulate.
For carbon fiber skirts, apply a UV protectant spray periodically to prevent yellowing or fading.
Check all screws and bolts every few months or after long drives.
Tighten any loose fasteners to prevent rattling or detachment.
Replace any corroded or damaged screws promptly.
Avoid harsh chemicals like gasoline or solvents near the skirts.
In winter, wash frequently to remove salt and road chemicals that can corrode metal fasteners.
Use quality car wax or polish on ABS or fiberglass skirts to maintain shine and add a protective barrier.
In hot summer months, avoid prolonged sun exposure which can degrade adhesives.
During winter, check for damage from snow, ice, or road salt.
Consider temporary removal if you live in areas with rough roads or heavy off-roading.
A car enthusiast documented the condition of their ABS plastic side skirts over three years. Regular cleaning and UV protection preserved the gloss and prevented structural damage, whereas a similar vehicle without maintenance showed fading and minor cracking.

In addition to side skirts, which enhance the car's sleek, sporty look, car owners also enjoy adding other key components to complete and personalize their look. Front splitters and rear spoilers are particularly popular. Front splitters significantly enhance the car's front's aggressive presence and ground contact, while rear spoilers add a more striking rear profile, and some designs even provide aerodynamic benefits.
