Trevora Carbon PR-1 Side Skirts for G80 BMW M3

The side profile is one of the most read angles on the G80 M3 and G81 M3 Touring, and the PR-1 skirts are built to make it work harder. The design adds a wider, more planted visual stance to the lower body, reinforcing the M3’s aggressive character from every approach angle and giving the car a lower optical center that reads as more purposeful from the side and at three-quarter rear. The effect is proportional; the skirts extend and sharpen the lower body line without introducing visual elements that compete with the factory M3 design language. Beyond the visual contribution, the PR-1 side skirts were extensively tested across varied road surfaces and driving conditions before release, with the design developed to manage airflow along the lower body panels in a way that contributes to improved stability at speed and a more balanced aerodynamic package front to rear. This functional testing underpins the performance claims in the listing rather than aerodynamic theory alone.

Carbon Fiber Construction

• Constructed using high-quality autoclave-cured pre-preg carbon fiber for superior strength-to-weight ratio. Each component is engineered and prototyped in-house using advanced CAD modeling and 3D scanning to achieve precise factory-plus fitment. A UV-resistant clear coat protects the clean weave pattern and maintains finish quality over time, ensuring long-term durability in both daily driving and high-performance environments.

Frequently Asked Questions

• What vehicles are the TREVORA PR-1 side skirts compatible with? The TREVORA PR-1 Pre-preg Carbon Fiber Side Skirts are compatible with the 2021 and newer BMW M3 Sedan G80 and the 2022 and newer BMW M3 Touring G81. Fitment on other BMW models, including the G82/G83 M4, is not confirmed.
• Were the PR-1 side skirts aerodynamically tested before release? Yes. The PR-1 side skirts were extensively tested across varied road surfaces and driving conditions during development, with the design refined to manage airflow along the lower body panels in a way that contributes to improved stability at speed and a more balanced aerodynamic package. The aerodynamic performance claims are based on this testing rather than theoretical modeling alone.
• Does the set include both left and right skirts? Yes. The TREVORA PR-1 side skirt set includes both the left and right skirts as a complete pair. No additional purchase is required to cover both sides of the vehicle.
• Can these skirts be installed at home or is professional fitting required? TREVORA validated the fitment of the PR-1 side skirts on multiple G80 and G81 vehicles before release and confirmed the installation is suitable for at-home fitting using standard hand tools. No drilling or specialist equipment is required. Professional installation is still recommended for best results, particularly to ensure consistent adhesive contact and correct alignment across the full length of both skirts.
• Do the side skirts require drilling or permanent modification to the vehicle? No. The PR-1 side skirts are designed for non-invasive installation using pre-applied 3M double-sided automotive tape and the included assembly hardware. No drilling or permanent modification to the factory rocker panels or vehicle structure is required.
• What is the 2×2 dry weave pre-preg carbon fiber and how does it differ from standard wet-laid carbon? The 2×2 dry weave refers to the weave pattern of the carbon fiber fabric, which produces a consistent checkerboard-style surface pattern across the panel. Pre-preg manufacturing pre-impregnates the fabric with a controlled resin ratio before forming and curing, producing superior resin consistency compared to wet-laid carbon where resin is applied manually. The result is a more uniform surface finish and better structural integrity. On a full-length side skirt that runs the complete length of the rocker panel and is visible at close range, the consistency of the weave across both skirts from front to rear is directly apparent; pre-preg dry weave construction ensures both skirts carry the same surface quality throughout.
