As an important part of the exterior kit, side skirts have long surpassed the simple decorative significance. They are like the "battle skirts" of your car, outlining dynamic lines while speeding and showing the owner's taste in details. However, choosing side skirts is not an easy task. Issues such as material, design, matching, practicality,and supplier reliability are intertwined, often making car ownersentangled. Choosing the perfect side skirt for your car is not only about upgrading the appearance, but also a comprehensive consideration of performance, protection, and personality. This ultimate guide will take you to an in-depth understanding of all aspects of side skirts and help you make a wise decision.
As the name implies, automotive side skirts are plate-shaped or skirt-shaped parts installed below the doors on both sides of the vehicle and between the front and rear wheel arches. It is not an invention of modern cars, and its prototype can be traced back to the deflectors added to early racing cars to optimize the airflow of the chassis. With the development of the automobile industry, side skirts have gradually evolved from functional parts to key modified parts with both aerodynamic performance and aesthetic value.
The core aerodynamic function of the side skirts is to seal the gap under the side of the car body. When the vehicle is driving at high speed, a large amount of air will rush under the chassis, generating lift and induced drag.
The side skirts directly cover the outside of the body side beams, forming an additional layer of physical protection. The gravel and sand rolled up by the wheels during driving are the "natural enemies" of the original side beam paint. The side skirts can effectively withstand most impacts and prevent the paint from cracking and rusting.
The side skirts fill the visual gap under the doors, making the side lines of the car body more complete and smoother, visually significantly lowering the height of the car body and creating a sense of sportiness or luxury as if flying close to the ground.
The lower part of the original vehicle door sill usually exposes welding seams, sealants, wiring harnesses (especially electric vehicles) or some chassis structures, which makes the visual effect not neat. The side skirts can perfectly cover these unsightly parts, making the lower part of the vehicle side look cleaner, smoother and more refined, and improving the overall craftsmanship and completion.
The side skirts themselves are additional parts, and their purchase cost is not cheap. As mentioned earlier, scratches, dragging, collisions, and even improper car washing may cause damage to the side skirts. Repairing or replacing the side skirts is an additional expense compared to the original state without side skirts.
Poor quality materials can easily lead to product brittle deformation, fading, cracking, poor paint adhesion and falling off. Improper installation can cause the side skirts to vibrate, make abnormal noises while driving, or even fall off at high speeds, causing serious accidents!
Although the weight of the side skirts is limited, as an additional component, it does increase the weight of the car. For ordinary civilian vehicles, this weight increase has little effect on performance and can be completely ignored. However, for track racing vehicles that pursue extreme lightweight, any additional weight needs to be carefully weighed, and the advantages of carbon fiber are more prominent at this time.

Lip type: The most common and conservative style. The design is simple, and it only extends slightly from the bottom of the original car side beam to form a slender "lip". The main function is to lower the visual center of gravity, provide the most basic protection and a slight aerodynamic effect. The advantage is that it is highly integrated with the original car and does not affect the passability. It is suitable for original factory upgrades or low-key modifications. Commonly seen in original factory sports kits. Side skirt: More three-dimensional and prominent than lip skirt. The side skirt itself has a certain height and thickness, like a "fence" wrapping the lower part of the car body. It can more effectively protect the door sill and visually significantly increase the thickness and power of the car body. There are many design changes, and simple lines or grooves can be added to the surface. It balances visual effects and practicality.
The lines and curves of the side skirts are the key to reflecting the sense of design. Sharp fold lines bring a sense of combat; smooth curves convey a sense of elegance; complex multi-layered structures appear to be full of technology. The extension of the waistline and the transition treatment at the wheel arch are crucial. The front vents can guide the airflow into the wheel arch to dissipate heat for the brakes; the fins or air ducts on the side can comb the side airflow, reduce turbulence, or guide the airflow to the rear diffuser. The design must comply with the principles of aerodynamics, otherwise it may be counterproductive. Commonly seen in racing style side skirts.
Reduced passability is the most troublesome disadvantage of side skirts, especially in areas with complex road conditions.Prioritize lip-type side skirts. This type of design has the smallest droop and the least impact on passability. Sacrifice some visual effects in exchange for maximum practicality. Ask the supplier for detailed dimensional drawings or measured data of the target side skirts, focusing on the additional droop height relative to the original vehicle installation point after installation.
Different uses have completely different requirements for the material, weight and durability of the side skirts. Buyers need to purchase according to their own needs, whether they are pursuing a cool appearance or improving the protection of the car body.
Buy side skirts developed for your specific model year. Body lines may vary between generations and facelifts. Make sure the supplier clearly states that the product is suitable for your car.Ask the supplier to provide installation renderings or videos of the actual vehicle of the model to observe the fit, gap control, and smoothness of lines. A good product should look like an original part.
Understand the reputation of different brands. Focus on: mold opening accuracy, material durability, paint quality, packaging and transportation protection, and after-sales service. Choose a supplier that focuses on automotive exterior parts, has mature development and production experience, and can provide detailed product information and after-sales guarantee, such as AMP-Z.
The installation of side skirts needs to be evaluated based on your own hands-on ability. Simple lip-type side skirts can be installed independently with strong double-sided adhesive. When encountering complex side skirt installation, especially those that require precise positioning and drilling and fixing, it is strongly recommended to hand it over to a professional modification shop. Improper installation can cause serious consequences.
1.Accuracy guarantee: The technicians are experienced and familiar with the structures of different models. They can accurately locate the side skirts to ensure left-right symmetry, front-to-back alignment, and uniform gaps to achieve the best visual effect.
2.Reliable process: Master the correct cleaning, grinding, applying adhesion promoter, pasting, punching, and fixing techniques to ensure that the bonding is firm and reliable, and the screws are fixed in place without damaging the car body.
3.Risk avoidance: Avoid serious consequences such as damage to the side skirts, damage to the original car paint or sheet metal, and loose fixation due to improper operation.Save worry and effort: Professional tools and venues, high efficiency, and guaranteed results. Especially for complex side skirts.
·Park the vehicle in a level, well-lit, clean work area.
·Clean the installation area thoroughly and wipe it repeatedly to remove oil, wax stains, and dust to ensure it is absolutely clean and dry.
·Prepare all tools, tape measure, marker, tape, heat gun, adhesion promoter, special screwdriver, etc.
·Use a tape measure to ensure that the height and front and rear positions of the left and right side skirts are completely symmetrical, and use a level ruler to assist in the inspection.
·Use tape or low-viscosity tape to temporarily fix the side skirt position.
·Carefully check the uniformity of each gap between the side skirt and the body, and whether the overall lines are smooth and natural. Repeatedly adjust until perfect.
·Tear off the release paper on one side of the 3M tape, and carefully and evenly stick the tape to the designated bonding area on the inside of the side skirt.
·When the adhesion promoter reaches the best state, align the side skirt accurately to the previously marked position at one time and press it firmly into place.
·Using a hot air gun to moderately heat the bonding area can significantly activate the tape's viscosity and improve the final strength.
·Remove any temporary securing tape
·Thoroughly check the side skirt installation position, fit, and gaps again.
·Clean fingerprints, adhesion promoter traces, etc. left during the installation process.
·Inaccurate positioning: causes the side skirt to be skewed, asymmetric, uneven gaps, and extremely poor visual effects. Repeated measurement and adjustment are required.
·Incomplete cleaning: Residual oil on the bonding surface is the main reason for the failure and fall of double-sided adhesive! Cleaning must be strict.
·Improper use of adhesion promoter: Not applying, applying too little, or pasting before it is completely dry will seriously affect the adhesion.
First, use a low-pressure water gun to wash away the dust and sand on the surface. Use a car wash liquid with a neutral pH value, and use a soft sponge or car wash gloves to gently scrub the surface of the side skirt. Avoid using a hard brush or strong alkaline detergent, which will scratch the paint or accelerate the aging of the plastic. Pay special attention to cleaning the bottom edge of the side skirt and the seam with the car body, where sand and dirt are easily accumulated. Rinse thoroughly to avoid car wash liquid residue. Dry with a clean microfiber towel or air dry.

To create a perfect posture for their car, car owners often match these parts in addition to the side skirts:
If it is just a surface scratch or a small area of paint peeling, local repair and painting can be done. If it is a stress-bearing part or a large area of damage, replacement is a safer and more reliable option.
Anti-flying stones and gravel: The effect is remarkable. It is one of the most core protection functions of the side skirts, effectively preventing the gravel rolled up by the wheels from hitting the original side beam paint surface, preventing paint peeling and rusting.
It is recommended to clean the side skirts every time you wash your car. This is the most worry-free way. After driving on muddy roads, snowy days, or at the seaside, the chassis and side skirts should be thoroughly cleaned as soon as possible to remove corrosive substances.
