Why G37 Sedan Side Skirts Are Necessary

From my experience, adding side skirts to my G37 Sedan made a noticeable difference in both appearance and performance. First, they give the car a much sportier and aggressive look, which instantly elevates the overall style. I love how the side skirts visually lower the car, making it appear more grounded and sleek.

Beyond aesthetics, side skirts also help improve aerodynamics. When I drive at higher speeds, the side skirts reduce the amount of air flowing underneath the car, which minimizes lift and enhances stability. This makes the handling feel more planted and responsive, especially during sharp turns.

Lastly, side skirts provide some protection to the lower sides of my G37 from road debris and small scrapes. This helps keep the bodywork looking clean and preserves the value of the car over time. For me, the combination of style, improved driving dynamics, and added protection makes side skirts a necessary upgrade for the G37 Sedan.

My Buying Guide on ‘G37 Sedan Side Skirts’

When I decided to upgrade my Infiniti G37 Sedan, adding side skirts was one of the best aesthetic and functional enhancements I made. If you’re considering the same, here’s what I learned through the process to help you choose the right side skirts for your G37 Sedan.

Understanding What Side Skirts Do

Side skirts aren’t just for looks—they improve your car’s aerodynamics by smoothing airflow along the sides, which can help with stability at higher speeds. For me, they added a sleek, aggressive look that really set my G37 apart from others on the road.

Material Choices: What Worked for Me

Side skirts come in various materials, including ABS plastic, fiberglass, polyurethane, and carbon fiber. I went with polyurethane because it offered a great balance of durability and flexibility, which is important since side skirts can be prone to scrapes from curbs or speed bumps. If you want something lighter and more performance-oriented, carbon fiber is a premium option but comes at a higher price.

Fitment and Compatibility

A perfect fit is crucial. I made sure to buy side skirts specifically designed for the G37 Sedan model year I own. Universal side skirts might seem cheaper, but they often require modifications and don’t look as seamless. OEM-style or model-specific aftermarket parts gave me confidence in proper fitment and easier installation.

Style and Design Preferences

Side skirts come in a range of styles—from subtle OEM replacements to aggressive, extended designs. I chose a style that complemented my car’s existing lines without being too flashy. Consider your personal taste and whether you want a subtle upgrade or a standout, sporty look.

Installation Considerations

I opted for side skirts that could be installed with basic tools and minimal modifications. Some kits come with pre-drilled holes and mounting hardware, which made my installation process much smoother. If you’re not comfortable with DIY, factor in the cost of professional installation.

Price Range and Budgeting

Prices vary widely depending on material, brand, and style. I set a budget beforehand and found good-quality polyurethane skirts that fit within it. Remember to also budget for paint matching and installation if needed.

Maintenance and Durability

Since side skirts are close to the ground, they can get scratched or damaged. I learned that polyurethane skirts handle minor impacts better and are easier to repair than fiberglass. Regular cleaning and occasional touch-ups keep them looking fresh.

Where to Buy

I found reputable sellers online and local performance shops that specialize in Infiniti parts. Reading reviews and checking return policies helped me avoid common pitfalls.

Final Thoughts

Adding side skirts to my G37 Sedan was a rewarding upgrade that enhanced both style and aerodynamics. By focusing on material quality, fitment, and style, I got a set that I’m proud of and that stands up well to daily driving. I hope my experience helps you make an informed choice for your own ride!
