Installing wide side skirts on your Lexus RX represents a significant modification that can transform both the visual appeal and functional characteristics of your luxury SUV. This comprehensive guide explores every aspect of wide side skirt installation, from aesthetic enhancements and aerodynamic benefits to potential drawbacks and practical considerations. Whether you're a performance enthusiast looking to optimize your vehicle's handling or simply want to give your RX a more aggressive stance, understanding the full scope of this modification will help you make an informed decision.
Understanding Wide Side Skirts and Their Purpose
Wide side skirts are aerodynamic panels that attach to the lower edges of your Lexus RX's body, running along the sides between the front and rear wheels. Unlike standard side skirts that come with some trim levels, wide side skirts extend further outward and downward, creating a more pronounced visual effect and potentially offering enhanced functional benefits. These aftermarket components serve multiple purposes beyond mere decoration.
The side skirt of a car consists of special aerodynamic panels that remain attached to the edge present below in the body of a four-wheeler, with the typical design running from the front to the back wheels and installed not only for aesthetics but also to serve practical functional purposes. For the Lexus RX specifically, wide side skirts can dramatically alter the vehicle's profile, making it appear lower, wider, and more planted on the road.
The primary functions of side skirts include streamlining airflow along the vehicle's sides, reducing aerodynamic drag, and improving stability at higher speeds. From a visual standpoint, they create a sportier, more aggressive appearance that distinguishes your RX from standard models. The "wide" designation typically means these skirts extend beyond factory specifications, offering even more dramatic styling and potentially greater aerodynamic effects.
The Comprehensive Advantages of Wide Side Skirts
Enhanced Visual Appeal and Aggressive Styling
The most immediately noticeable benefit of installing wide side skirts on your Lexus RX is the dramatic transformation in appearance. Wide side skirts give your luxury SUV a sportier, more aggressive stance that commands attention on the road. The extended profile creates a visual connection between the front and rear of the vehicle, producing a cohesive, ground-hugging aesthetic that suggests performance and sophistication.
From an aesthetic point of view, the vehicle receives the appearance of being sporty and sleek, making it appear a bit lower and effectively enhancing the overall visual and aesthetic appeal of the vehicle concerned. This lowered appearance is particularly desirable for Lexus RX owners who want their vehicle to stand out from the crowd while maintaining the refined elegance associated with the Lexus brand.
Wide side skirts can also help visually balance the proportions of the RX, which is a relatively tall SUV. By extending the lower body lines outward, these modifications create the illusion of a wider track and lower center of gravity, giving the vehicle a more athletic and purposeful appearance. This aesthetic enhancement can be particularly striking when combined with other modifications such as lowered suspension, larger wheels, or complementary front and rear bumper treatments.
Improved Aerodynamic Performance
Beyond aesthetics, properly designed wide side skirts offer genuine aerodynamic benefits that can enhance your Lexus RX's performance characteristics. By reducing the airflow that directly hits the rear tire, the grounding property of the rear tire is improved, and pressure between wheelbases is reduced by pulling air under the floor. This aerodynamic management becomes increasingly important at highway speeds.
Side skirts not only provide visual enhancement, but will also improve aerodynamics of your car by increasing downforce. The increased downforce helps keep your RX more stable during high-speed driving, cornering, and lane changes. This improved stability can translate to better handling characteristics and increased driver confidence, particularly during spirited driving or adverse weather conditions.
The side skirts in cars eventually aid in reducing turbulence beneath the vehicle, which improves handling and stability, especially during highway speedy driving and cornering. By managing the airflow more effectively, wide side skirts help minimize the amount of turbulent air passing underneath the vehicle, which can create lift and instability. This streamlined airflow can also contribute to reduced wind noise and a quieter cabin experience at highway speeds.
Some enthusiasts report modest improvements in fuel efficiency due to reduced aerodynamic drag, though the actual gains depend on numerous factors including driving speed, skirt design, and overall vehicle configuration. While you shouldn't expect dramatic fuel economy improvements, the side skirts in cars essentially contribute to enhanced fuel efficiency by maintaining an economical approach.
Protection from Road Debris and Minor Damage
Wide side skirts provide a practical protective function that many owners appreciate. The side skirts in cars act as a barrier, preventing gravel, rocks, and other road debris from damaging the body of the vehicle, which effectively preserves the exterior look of the car. This protective barrier is particularly valuable if you frequently drive on gravel roads, construction zones, or areas where road debris is common.
The lower rocker panels of your Lexus RX are vulnerable to stone chips, scratches, and minor impacts from road hazards. Wide side skirts create an additional layer of defense, absorbing minor impacts that might otherwise damage the vehicle's painted body panels. This protection can help maintain your RX's resale value by preventing unsightly damage to these vulnerable areas.
Additionally, side skirts can help protect against minor parking lot mishaps, such as scrapes from curbs or contact with low barriers. While they won't prevent all damage, they do provide an extra measure of protection for the lower body panels that are most susceptible to everyday wear and tear.
Customization and Personalization
Installing wide side skirts allows you to personalize your Lexus RX and make it uniquely yours. With numerous styles, materials, and finishes available, you can select side skirts that perfectly match your aesthetic preferences and complement other modifications you've made or plan to make. This level of customization helps your vehicle stand out and reflects your personal taste and style.
Wide side skirts are often part of a complete body kit or aero package, allowing you to create a cohesive, integrated look when combined with matching front splitters, rear diffusers, and other aerodynamic components. This coordinated approach to styling can transform your RX from a standard luxury SUV into a distinctive, head-turning vehicle that showcases your commitment to automotive aesthetics.
The Potential Drawbacks and Challenges
Significant Financial Investment
One of the primary considerations when contemplating wide side skirts is the substantial cost involved. High-quality wide side skirts designed specifically for the Lexus RX can be expensive, and that's before factoring in professional installation and painting. The total investment can range from several hundred to several thousand dollars depending on the brand, material, and complexity of the installation.
Depending on the make and model of the vehicle and the material of the side skirts, the installation costs may range between INR 5000 and INR 25000, with Original Equipment Manufacturer side skirts being even pricier because of their quality and compatibility with specific car makes. When converted to US dollars, professional installation and painting can easily add $200 to $500 or more to the cost of the parts themselves.
Premium materials like carbon fiber command even higher prices due to their specialized construction and lightweight properties. Side skirts are made from various materials such as fiberglass, polyurethane, carbon fiber, or ABS plastic, with carbon fiber skirts generally costing more to repair or replace due to their specialized construction and higher material cost. You'll need to carefully consider whether the aesthetic and functional benefits justify this significant financial outlay.
Beyond the initial purchase and installation, there are ongoing costs to consider. Installing side skirts by professional experts might prove to be expensive, and regular maintenance of side skirts can prove to be expensive which includes regular cleaning, occasional repairs, etc., enhancing the overall cost of owning the vehicle.
Increased Vulnerability to Damage
While side skirts can protect your vehicle's body panels, the skirts themselves are highly vulnerable to damage. Wide side skirts extend further from the vehicle's body, making them more susceptible to scraping on curbs, speed bumps, steep driveways, and uneven terrain. This increased exposure means you'll need to be more cautious when parking, navigating tight spaces, or driving on rough roads.
Side skirts face constant exposure to road hazards, curbs, and scraping damage. The wider the skirts, the greater the risk of contact with obstacles that a standard RX would clear without issue. This vulnerability is particularly problematic in urban environments with tight parking spaces, high curbs, and narrow streets.
Damage to side skirts can be costly to repair. Minor cosmetic repairs cost $50 to $150, moderate repairs involving filling cracks and repainting cost $150 to $400, while severe damage or replacement can cost $400 to $1,200 or more, especially with OEM parts or carbon fiber components. These repair costs can quickly add up if you frequently damage your side skirts, potentially negating any protective benefits they provide.
The material composition of your side skirts also affects their durability and repair costs. Fiberglass skirts can crack upon impact, polyurethane offers more flexibility but can still tear or deform, and carbon fiber, while lightweight and strong, is expensive to repair or replace when damaged.
Reduced Ground Clearance
Wide side skirts, by their very nature, reduce your Lexus RX's effective ground clearance. This reduction can create practical challenges in everyday driving situations. Steep driveways, speed bumps, parking lot entrances, and uneven road surfaces that your stock RX could navigate without issue may now require careful maneuvering or complete avoidance.
The Lexus RX is designed as a luxury crossover SUV with reasonable ground clearance for varied driving conditions. Installing wide side skirts compromises this versatility, making your vehicle less suitable for light off-road use, unpaved roads, or areas with poor road conditions. If you live in an area with harsh winters, deep snow, or frequently encounter rough terrain, wide side skirts may prove impractical.
This ground clearance issue becomes even more pronounced if you've also lowered your RX's suspension for improved handling and aesthetics. The combination of lowered suspension and wide side skirts can create a vehicle that requires constant vigilance to avoid scraping and damage, which can be frustrating in daily driving situations.
Installation Complexity and Fitment Issues
Proper installation of wide side skirts requires skill, precision, and often specialized tools. While some enthusiasts attempt DIY installation, professional installation is generally recommended to ensure proper fitment, secure attachment, and a finished appearance that meets quality standards. Professional auto body shops experienced in installation of visual modifications are highly recommended for installation.
Improper installation can lead to numerous problems including gaps between the skirts and body panels, rattling or vibration at highway speeds, premature detachment, and an overall unprofessional appearance. Some installations require drilling into the vehicle's body panels, which creates permanent modifications that cannot be easily reversed. This drilling also introduces potential entry points for moisture and rust if not properly sealed.
Aftermarket side skirts may not always offer perfect fitment, even when advertised as vehicle-specific. The side skirts in cars may not always be available for every make and model of vehicle, which limits the options for customisation and often needs custom modification and fabrication. Minor adjustments, trimming, or modification may be necessary to achieve proper alignment and appearance, adding to the installation complexity and cost.
Additionally, side skirts typically require painting to match your vehicle's color unless you opt for unpainted options like carbon fiber or matte black finishes. Professional paint matching and application add significantly to the overall cost and require additional time for proper preparation, application, and curing.
Legal and Insurance Considerations
Before installing wide side skirts, it's essential to understand the potential legal and insurance implications. Some jurisdictions have regulations regarding vehicle modifications, particularly those that alter the vehicle's dimensions or could pose safety concerns. Wide side skirts that extend significantly beyond the vehicle's original body lines may violate local regulations or require special permits.
Insurance considerations are equally important. Some insurance companies may view aftermarket body modifications as increasing the vehicle's value, which could affect your premium. Others may have concerns about modifications that alter the vehicle's safety characteristics or increase the likelihood of damage. It's crucial to inform your insurance provider about any modifications to ensure you maintain proper coverage.
In some cases, modifications may void certain aspects of your vehicle's warranty, particularly if the manufacturer determines that the modification contributed to a failure or problem. While side skirts are unlikely to affect powertrain components, they could potentially impact warranty coverage for body panels, paint, or related components.
Additionally, if you finance or lease your Lexus RX, you may need permission from the lender or leasing company before making significant modifications. Some lease agreements explicitly prohibit modifications or require that the vehicle be returned to stock condition at lease end, which would necessitate removing the side skirts and potentially repairing any mounting holes or damage.
Material Options and Their Characteristics
Wide side skirts are manufactured from various materials, each offering distinct advantages and disadvantages. Understanding these material options will help you select the best choice for your needs, budget, and intended use.
Fiberglass Side Skirts
Fiberglass is one of the most common materials for aftermarket body kits and side skirts. It offers a good balance of cost, weight, and durability, making it a popular choice among enthusiasts. Fiberglass side skirts are relatively affordable compared to other materials and can be easily repaired if damaged.
However, fiberglass has some drawbacks. It's more brittle than other materials and can crack upon impact, particularly in cold weather when the material becomes less flexible. Fiberglass side skirts typically require significant preparation work before painting, including sanding, filling, and priming to achieve a smooth, professional finish. The material can also be prone to stress cracks over time, especially around mounting points.
Polyurethane Side Skirts
Polyurethane (often called "urethane" or "poly") is a flexible, durable material that has gained popularity for automotive body components. Polyurethane side skirts offer excellent impact resistance and flexibility, making them less prone to cracking than fiberglass. This flexibility allows them to absorb minor impacts without sustaining permanent damage.
Polyurethane side skirts typically require less preparation work before painting compared to fiberglass, as they often come with a smoother finish from the manufacturer. However, they're generally more expensive than fiberglass options. The material's flexibility can also be a disadvantage in some applications, as polyurethane skirts may flex or deform under certain conditions, potentially affecting fitment and appearance.
ABS Plastic Side Skirts
ABS plastic is also primarily used in OEM parts throughout the automotive industry due to its impact, scratch resistance and shock absorbance characteristics. ABS (Acrylonitrile Butadiene Styrene) plastic offers an excellent combination of durability, impact resistance, and cost-effectiveness.
ABS side skirts are lightweight yet strong, resistant to temperature extremes, and relatively easy to repair if damaged. They typically come with a textured or smooth finish that requires minimal preparation before painting. The material's consistency and quality make it a reliable choice for side skirts, though it may not offer the same premium feel as carbon fiber or the flexibility of polyurethane.
Carbon Fiber Side Skirts
Carbon fiber represents the premium option for side skirts, offering the best strength-to-weight ratio of any material. Carbon fiber side skirts are significantly lighter than alternatives while maintaining excellent structural rigidity. The distinctive woven carbon fiber appearance is highly desirable among enthusiasts and can be left unpainted for a high-tech, motorsport-inspired look.
However, carbon fiber comes with a substantial price premium. Genuine carbon fiber side skirts can cost several times more than fiberglass or polyurethane alternatives. Additionally, carbon fiber is expensive to repair if damaged, and the material can be brittle, making it susceptible to cracking upon impact. Some manufacturers offer "carbon fiber" products that are actually fiberglass with a carbon fiber overlay, which reduces cost but also compromises the weight savings and structural benefits of true carbon fiber construction.
Installation Process and Considerations
Understanding the installation process for wide side skirts will help you appreciate the complexity involved and make informed decisions about whether to attempt DIY installation or hire professionals.
Professional Installation
Professional installation by an experienced body shop or automotive customization specialist is generally recommended for wide side skirts. Professionals have the tools, experience, and expertise to ensure proper fitment, secure attachment, and a high-quality finished appearance. They can also identify and address any fitment issues that may arise during installation.
Professional installation costs vary widely depending on location, shop rates, and the complexity of the specific side skirts being installed. Based on various automotive forums and industry sources, professional installation typically ranges from $150 to $400 for labor alone, not including painting. If painting is required, expect to add another $200 to $500 or more depending on the quality of paint work and whether color matching is necessary.
The installation process typically involves thoroughly cleaning the mounting surfaces, test-fitting the side skirts to identify any necessary adjustments, drilling mounting holes if required, applying adhesive or mounting tape, securing the skirts with screws or clips, and performing final adjustments to ensure proper alignment and gap consistency. Professional installers will also properly seal any drilled holes to prevent moisture intrusion and rust.
DIY Installation
Some enthusiasts choose to install side skirts themselves to save on labor costs. DIY installation is certainly possible, particularly for mechanically inclined individuals with appropriate tools and workspace. However, it requires patience, attention to detail, and careful planning to achieve professional-quality results.
The DIY installation process generally involves cleaning the rocker panels thoroughly with alcohol or degreaser, test-fitting the side skirts and marking mounting locations, drilling pilot holes if necessary (measuring multiple times to ensure accuracy), applying high-quality automotive mounting tape or adhesive, carefully positioning the side skirts and pressing firmly to ensure good adhesion, and installing any screws, clips, or fasteners according to the manufacturer's instructions.
Common DIY installation challenges include achieving consistent gaps between the side skirts and body panels, ensuring the skirts are level and properly aligned on both sides, drilling holes in the correct locations without damaging the vehicle, and achieving secure attachment that won't fail at highway speeds. Many DIY installers find that having a helper makes the process significantly easier, as side skirts can be awkward to position and hold in place while marking or fastening.
Painting and Finishing
Unless you opt for unpainted carbon fiber or pre-painted side skirts, you'll need to have your side skirts painted to match your Lexus RX's color. Professional paint work is highly recommended, as achieving a proper color match and durable, high-quality finish requires specialized equipment, materials, and expertise.
The painting process involves thorough cleaning and degreasing of the side skirts, sanding to create proper surface texture for paint adhesion, applying primer (multiple coats with sanding between coats), applying base coat in your vehicle's specific color code, applying clear coat for protection and gloss, and allowing proper curing time before installation. Professional paint shops will also perform color matching to ensure the painted side skirts perfectly match your vehicle's existing paint, accounting for any fading or color variation that may have occurred over time.
Some manufacturers offer pre-painted side skirts in common Lexus colors, which can save time and money. However, these may not perfectly match your specific vehicle due to paint batch variations or fading of your original paint. Factory-painted options from Lexus or TRD typically offer the best color match but come at a premium price.
Maintenance and Long-Term Care
Once installed, wide side skirts require ongoing maintenance to keep them looking their best and functioning properly. Regular cleaning is essential, as side skirts accumulate road grime, brake dust, and debris more readily than other body panels due to their low position. Use gentle automotive cleaning products and soft brushes or microfiber cloths to avoid scratching the finish.
Periodically inspect the mounting points and fasteners to ensure everything remains secure. Vibration and stress from driving can cause screws to loosen over time, and adhesive can degrade with exposure to heat, cold, and moisture. Tighten any loose fasteners and address any separation between the side skirts and body panels promptly to prevent further damage.
Check for cracks, chips, or damage regularly, particularly after driving on rough roads or if you've scraped a curb or obstacle. Small chips and scratches can be touched up with matching paint to prevent them from worsening. More significant damage may require professional repair or replacement of the affected section.
In winter climates, be particularly vigilant about ice and snow buildup around the side skirts, as this can create additional stress on mounting points and potentially cause damage. Road salt can also accelerate corrosion of metal fasteners and damage paint, so thorough cleaning during winter months is especially important.
Compatibility with Other Modifications
Wide side skirts are often part of a broader vehicle customization plan. Understanding how they interact with other modifications will help you create a cohesive, well-integrated appearance and avoid compatibility issues.
Suspension Modifications
Lowering springs or coilover suspension systems are popular modifications that complement wide side skirts aesthetically. The combination of lowered ride height and extended side skirts creates an aggressive, ground-hugging appearance that many enthusiasts desire. However, this combination also significantly reduces ground clearance, making the vehicle even more susceptible to scraping and damage.
If you plan to lower your Lexus RX, carefully consider the total reduction in ground clearance when combined with wide side skirts. Some enthusiasts find that the combination is too extreme for practical daily driving, particularly in areas with poor road conditions or aggressive speed bumps.
Complete Body Kits
Wide side skirts are often designed as part of a complete body kit that includes front bumper covers, rear bumper covers, and sometimes fender flares or other components. For the best effect and best styling, it is recommended to install the TRD JAPAN Front Spoiler, Rear Skirt with Rear Diffuser, and Rear Gate Wing Spoiler for RX F SPORT together. Installing the complete kit creates a cohesive, integrated appearance that looks more professional than mixing and matching components from different manufacturers.
However, complete body kits represent a significant financial investment and installation commitment. If you're considering a complete kit, plan the entire project carefully and budget accordingly. Some enthusiasts prefer to install components gradually, but this approach can result in mismatched styling or fitment issues if components from different manufacturers don't work well together.
Wheel and Tire Modifications
Wide side skirts often look best when paired with wider wheels and tires that fill the wheel wells more completely. The extended side profile created by wide skirts can make standard wheels appear undersized or recessed. Upgrading to wider wheels with appropriate offset can create a more balanced, aggressive appearance that complements the wide side skirts.
However, wheel and tire modifications must be carefully planned to avoid rubbing issues, particularly if you've also lowered the suspension. Consult with wheel fitment specialists to ensure your chosen wheel and tire combination will work properly with your wide side skirts and any other modifications you've made.
