MHC Plus Carbon Side Skirt Extensions for BMW M4 G82 and G83

Give your M4 a sharper, lower and more purposeful silhouette with these autoclaved carbon side skirt extensions from MHC Plus.

These carbon rocker extensions have clip positions and hole locations that mirror the original under-sill trims, so alignment is straightforward and the finish looks factory. The profile follows the M4’s body lines perfectly, delivering a cohesive, motorsport-inspired look without compromise.

Real-world feedback

We have fitted these side skirt extensions to our own cars and for customers, and the response has been consistently positive. Owners praise the spot-on fitment, the flawless lacquer and the way the fin detail cleans up the side of the car. It looks right, fits right and feels premium.

Pre-preg carbon advantages

• Stronger and more resilient than wet lay parts for daily-driven cars
• Smoother surface straight from the mould for a cleaner, more uniform finish
• Lighter weight for performance-focused builds

Complete the look

For a cohesive aesthetic, pair these side skirts with the matching MHC Plus front splitter and rear bumper corner pieces in the same finned design to create a balanced carbon styling package.
