MHC Plus SK1 Pre-Preg Carbon Fibre Side Skirts for BMW G80 M3 & G82 M4 Competition (2021+) – OEM-Style 3k 2x2 Gloss, UK-Made G8X

Autoclaved Dry Carbon Rocker Extensions for BMW G80 M3 and G82 M4 by MHC Plus

Give your G8X chassis a sharper, lower and more purposeful stance with MHC Plus SK1 dry carbon rocker extensions. Hand made in England using pre-impregnated carbon fibre cured in an autoclave, these factory-look sill blades deliver a premium finish, tight tolerances and a true performance aesthetic. If you want lightweight side aero that looks like it rolled out of Munich, this is the upgrade.

Why enthusiasts pick SK1

• UK engineered using full 3D vehicle scans for consistent, repeatable alignment on the G80 Saloon and G82 Coupe.
• Factory-look styling that sits neatly beneath the OE gloss black sills to visually lower the car and sharpen the profile.
• Autoclave-cured pre-preg construction for high strength, crisp definition and a deep, high-gloss clearcoat.
• Twill weave face to complement other carbon trim pieces on the G8X platform.
• Noticeably lighter than wet-lay alternatives while remaining rigid and durable.
• Supplied with pre-applied high-bond tape and correctly sized stainless fixings for a secure installation.

Engineered fit and finish

MHC Plus utilises precision scan data of the G8X body to create rocker blades that follow the original sill geometry. The result is a snug, OEM-plus look without gaps or waviness. The edges are crisp, the weave presentation is consistent and the gloss finish is show-car ready.

What our team thinks

We have fitted SK1 sets in-house and the fitment has been spot on. Customers consistently comment on the weave quality, the way the car looks lower without being shouty and how well these blades tie in with other subtle aero pieces.
