2021–2024 BMW M4 G82 / G83 Side Skirt Extensions – Pre-Preg Dry Carbon Fiber
Upgrade the side profile of your BMW G82 or G83 M4 with these pre-preg dry carbon fiber side skirt extensions. Supplied as a handed pair, they extend the factory rocker lines for a lower, more aggressive stance with a premium exposed-weave finish.
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 durability, 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 skirt profile sharpens the lower body lines and visually lowers the car for a more planted look
- Carbon aesthetic: Refined 3K twill dry carbon weave and high-gloss finish deliver premium contrast against the factory paint
- Factory-style integration: Precision-molded for clean alignment with the factory body lines and rocker panels
Fitment
- 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 × carbon fiber side skirt extensions (left and right)
- Mounting hardware
Installation
- Screw-mounted: Secures with the included mounting hardware — no major modifications required
- Drilling required: Screw fixing pierces the rocker panel, so this is a permanent modification rather than a reversible fit
- Check orientation: The extensions are handed — confirm correct left and right sides before fitting
- Alignment: Dry-fit both panels and check height and fore-aft position match on each side before driving any screws
- Professional installation recommended for correct positioning, symmetrical alignment, and a clean finish along the full length
Before You Install
- Confirm your car is a G82 M4 Coupe or G83 M4 Convertible (2021–2024) before ordering
- This is a permanent, screw-mounted fitment — dry-fit both panels and confirm placement carefully before driving any screws, as holes cannot be undone
- Dry-fit both panels first — any difference in height or position between sides is visible along the car
- Side skirts sit low and are exposed to kerbs and driveway ramps — take care when parking
