BMW G82 / G83 M4 Real Carbon Fiber Side Skirt Extensions - Viper Style Kit | Fits 2021–2025 M4 Coupe & Convertible including Competition

Transform the side profile of your BMW M4 G82/G83 with the Viper Style Carbon Fiber Side Skirt Extensions.

Designed specifically for the 2021–2025 M4 Coupe and Convertible, this kit delivers a sharper, more aerodynamic aesthetic with functional side aero designed to complement the M4’s muscular factory body lines.

Key Features

• Authentic Carbon Fiber Construction – Crafted from real carbon fiber with a UV-protected gloss finish for maximum strength, lightweight performance, and long-term clarity.
• Viper Style Design – Features layered edges and an angular, high-performance silhouette that extends the factory side skirts, giving the car a track-ready stance.
• Enhanced Ground Effect – Visually lowers the vehicle by extending the rocker panel line closer to the road, creating an aggressive, planted look.
• Wider Floor Appearance – The bold side profile adds visual width to the M4, enhancing its road presence while optimizing side airflow.
• Functional Aerodynamics – Channels air more efficiently along the body’s sides, helping to reduce drag and stabilize the car at higher speeds.
• Direct OEM+ Fitment – Designed for a precise, clean installation with pre-drilled holes, mounting hardware, and automotive-grade adhesive tape included.

Design Integration: Aggressive Meets OEM+ Precision

The G82/G83 M4’s bold fenders and chiseled side lines are amplified by the Viper Style extensions, which seamlessly extend the lower body profile for a wider, lower, and more purposeful stance. The design integrates perfectly with other carbon fiber upgrades such as front lips, rear diffusers, and mirror caps — completing a cohesive, performance-driven aesthetic.

FITMENT:

• 2021–2025 BMW G82 M4 Coupe (incl. Competition)
• 2021–2025 BMW G83 M4 Convertible (incl. Competition)

Pair your Viper Style Side Skirt Extensions with our Viper Front Lip and Rear Diffuser for a complete OEM+ carbon fiber aero kit that enhances both performance and street presence.

IMPORTANT NOTE: These side skirts are constructed from genuine carbon fiber materials and requires precise handworked molding. This process ensures superior quality and improved fitment accuracy compared to mass-produced alternatives. Unlike dropshipped items, each set is individually molded, manufactured, quality control checked, and shipped directly by BAVMODS®. Because of this careful production process, please allow approximately 2 weeks from order placement to delivery.
