The Infiniti G37 is widely admired among car enthusiasts for its refined balance between luxury and sportiness. As part of Nissan’s premium Infiniti line, the G37 became a strong contender in the mid-range luxury sports coupe and sedan segment, drawing attention for its sharp handling, aggressive design, and reliable V6 engine. However, as with most performance-oriented vehicles, owners often look for ways to enhance both appearance and functionality. One of the most popular upgrades for this platform is the addition of carbon fiber side skirts.
Side skirts are aerodynamic components installed along the sides of a vehicle beneath the doors, and when crafted from carbon fiber, they add not only functionality but also a bold and stylish visual appeal. For G37 owners, carbon side skirts represent an upgrade that aligns with the car’s sporty DNA, creating a blend of aesthetics, performance, and individuality.
This guide will take you through a comprehensive journey of understanding G37 carbon side skirts—what they are, why they matter, their benefits, installation, maintenance, and how they compare to other materials and upgrades.
Understanding Side Skirts
Side skirts are part of a vehicle’s aerodynamic body kit. Their primary purpose is to manage airflow along the sides of the car and minimize turbulence that occurs beneath the chassis. When a vehicle moves at high speeds, air rushes under it, creating drag and lift that can destabilize handling. Side skirts act as barriers, reducing the amount of air that flows beneath the car and instead redirecting it smoothly along the sides.
For performance cars like the Infiniti G37, this aerodynamic improvement translates into more stable cornering, reduced drag, and a sportier driving feel.
Why Carbon Fiber for Side Skirts?
Carbon fiber is one of the most advanced materials in automotive manufacturing and motorsport engineering. It is composed of thin strands of carbon atoms bonded together to form a lightweight yet incredibly strong material. For side skirts, carbon fiber offers several advantages:
- Lightweight Strength: Carbon fiber is lighter than steel or fiberglass yet many times stronger, making it ideal for performance applications.
- Aesthetic Appeal: The woven carbon fiber pattern adds a high-end, race-inspired look to the G37.
- Durability: Resistant to rust, corrosion, and minor impacts, carbon fiber side skirts last longer under various conditions.
- Performance-Oriented Design: Carbon fiber is commonly used in supercars and race cars, giving the G37 a premium upgrade.
The Role of Side Skirts on the G37
The Infiniti G37 is already aerodynamically efficient, but the addition of carbon side skirts enhances its overall dynamics. Here’s how:
- Improved Airflow Management: By reducing turbulence underneath the car, the skirts stabilize airflow.
- Enhanced Cornering Stability: At higher speeds, the reduction of lift improves cornering grip.
- Sportier Appearance: Carbon side skirts create a lowered, aggressive stance that visually complements the G37’s lines.
- Integration with Other Body Mods: Skirts pair well with front splitters, rear diffusers, and carbon spoilers for a complete aerodynamic package.

Installation of Carbon Side Skirts on the G37
Installing carbon side skirts requires precision to ensure alignment and durability. While some enthusiasts choose DIY installation, professional fitting is highly recommended for best results.
Steps for Installation:
- Preparation:
- The car is washed and the side panels cleaned to remove dirt and debris.
- Skirts are test-fitted to confirm alignment.
- Mounting Method:
- Most carbon side skirts are installed using a combination of automotive-grade double-sided adhesive and self-tapping screws.
- Some high-end models may use custom brackets.
- Securing the Skirts:
- Adhesive tape is applied along the contact area.
- Skirts are carefully aligned and pressed firmly.
- Screws are then placed in concealed areas to add stability.
- Final Check:
- Edges are inspected for gaps.
- Adhesive is allowed to cure for 24–48 hours.
Maintenance of Carbon Side Skirts
While carbon fiber is strong, it requires proper care to maintain its appearance and longevity.
- Cleaning: Use mild car shampoo and microfiber cloths. Avoid abrasive cleaners.
- Wax or Sealant: Apply a carbon-specific sealant or ceramic coating to protect the finish.
- Avoid Impact: Be cautious around curbs and speed bumps since side skirts sit low.
- Inspect Regularly: Check for chips, scratches, or loose fittings.
Cost Considerations
The cost of G37 carbon side skirts depends on quality, brand, and finish.
| Type | Approximate Price Range (USD) |
|---|---|
| OEM-Style Carbon Skirts | $400 – $800 |
| Extended Racing Skirts | $700 – $1,200 |
| Forged Carbon Skirts | $1,000 – $1,800 |
| Custom Aftermarket Kits | $600 – $1,500 |
While cheaper fiberglass or ABS plastic skirts are available, carbon fiber’s superior durability and style often justify the higher cost.
Comparison: Carbon Fiber vs. Fiberglass vs. ABS Plastic
| Material | Strength | Weight | Durability | Appearance |
|---|---|---|---|---|
| Carbon Fiber | Excellent | Very Light | Long-Lasting | Premium, Exotic Look |
| Fiberglass | Moderate | Moderate | Prone to Cracks | Paint-Matched Look |
| ABS Plastic | Fair | Light | Less Durable | Affordable, Versatile |
Carbon fiber clearly stands out as the superior option for performance, aesthetics, and prestige.
Style and Visual Impact
For G37 enthusiasts, the addition of carbon side skirts is often about more than just performance. The lowered stance and sleek extension create an aggressive silhouette that transforms the vehicle’s character. Combined with other carbon accents like front lips, rear diffusers, or mirror caps, the car takes on a cohesive, high-performance identity.
G37 Sedan vs. Coupe: Skirt Considerations
While the sedan and coupe share the same platform, side skirt designs may differ slightly due to body dimensions.
- G37 Coupe: Sportier profile, skirts usually shorter and sleeker.
- G37 Sedan: Longer wheelbase requires extended skirt design for proper alignment.
Owners should ensure they purchase skirts specifically designed for their body style.
