Dry Carbon Fiber Side Skirt Extensions – BMW G80 M3 & G82/G83 M4 (2021+)

2021–2024 BMW M3 G80 / M4 G82 / G83 Side Skirt Extensions – Pre-Preg Dry Carbon Fiber

Complete the lower profile of your BMW G8X M3 or M4 with these pre-preg dry carbon fiber side skirt extensions. Supplied as a handed pair, the extended lip design sharpens the factory rocker panels and visually lowers the car for a more planted, performance-inspired stance.

Build

• Material: Pre-preg dry carbon fiber in a 3K twill weave — the resin is pre-impregnated into the weave under controlled conditions before curing, giving lightweight strength, a consistent weave, and a lighter finished component than standard wet carbon
• Manufacturing: Precision-moulded using 3D design and CNC machining
• Surface finish: High-gloss protective clear coat with a UV-resistant surface that helps maintain long-term finish quality
• Configuration: Supplied as a handed pair (left and right)

Design & Finish

• Aggressive stance: Extended lip design visually lowers the car and sharpens the side body lines for a more planted look
• Carbon aesthetic: Refined 3K twill dry carbon weave and high-gloss clear coat deliver premium contrast against the factory paint
• Factory-style integration: Precision-molded to follow the contours of the factory rocker panels for a clean, seamless fit

Fitment

• 2021–2024 BMW M3 (G80)
• 2021–2024 BMW M4 Coupe (G82)
• 2021–2024 BMW M4 Convertible (G83)
• Fits the factory rocker panels only — not compatible with aftermarket configurations

Package Contents

• 2 × dry carbon side skirt extensions (left and right)
• Mounting hardware

Installation

• Two mounting options: Fits using the included automotive-grade adhesive tape and screws for a secure fit — no major modifications required
• Drilling required for screw mount: Screw fixing pierces the rocker panel, so if you use the screw option this is a permanent modification rather than a reversible fit
• Surface prep: If using adhesive tape, thoroughly clean, degrease, and dry the rocker panel surface before fitting to ensure maximum adhesion
• Check orientation: The extensions are handed — confirm correct left and right sides before fitting
• Professional installation recommended for correct positioning, symmetrical alignment, and a clean finish along the full length

Before You Install

• Confirm your car is a G80 M3, G82 M4, or G83 M4 (2021–2024) before ordering
• Dry-fit both panels first — any difference in height or position between sides is visible along the car
• If using screws, mounting is permanent — confirm placement carefully before driving any screws, as holes cannot be undone
• Side skirts sit low and are exposed to kerbs and driveway ramps — take care when parking
