Dry Carbon Fiber G22 Side Skirts for BMW G22 G23 2021–2025

G22 Side Skirts for BMW 4 Series Aftermarket Programs

These G22 Side Skirts are model-specific add-on extensions for BMW 4 Series G22 Coupe and G23 Convertible vehicles from 2021–2025. The left-and-right set is developed for aftermarket distributors, BMW tuning brands, importers, body shops and professional installers that require genuine dry-carbon exterior components for resale. Its long lower profile and raised end fins create a more defined visual line along the vehicle’s rocker panels.

Part number WK-BMG22/G23-2125-CQ is manufactured from prepreg carbon fiber through autoclave molding. The standard version uses a 3K twill weave with a glossy clear surface. Matte finish, 12K weave and 18K weave programs can also be evaluated for wholesale, OEM, ODM and private-label orders.

G22 Side Skirts Product Specifications

Prepreg Dry Carbon and Autoclave Molding

The BMW 4 Series side skirts use prepreg carbon material with a controlled resin system. This construction creates a genuine carbon laminate rather than a printed carbon-look film or hydro-dipped surface. For B2B buyers, controlled material preparation supports more repeatable laminate quality and visible weave appearance across approved samples and production batches.

Autoclave curing uses controlled temperature and pressure to consolidate the long extension profile, raised fins and mounting surfaces. The process helps reduce excess resin and trapped air while supporting stable geometry. Final trimming, clear coating and inspection remain important because these are long, highly visible exterior parts installed close to the ground.

3K, Matte, 12K and 18K Appearance Options

The standard G22 Side Skirts feature 3K twill carbon under a glossy clear coat. This familiar weave can coordinate with front lips, mirror caps, spoilers and rear carbon parts. A matte finish is available when a lower-reflection appearance is required.

Optional 12K and 18K programs create a larger, more visible weave pattern. These should be treated as separate appearance specifications, not automatic substitutes for the standard 3K product. A physical sample or signed finish reference should be approved before bulk production, particularly when matching other components in a complete carbon package.

BMW G22 and G23 Fitment Verification

The listed application covers G22 Coupe and G23 Convertible vehicles from 2021–2025, but original rocker panels and lower trim may vary by market, trim package, production revision or previous repair. The pictured product is an add-on extension and should not be described as a complete factory rocker-panel replacement. Each order for G22 Side Skirts must be checked against the actual vehicle.

Information Required Before Ordering

• Full side photographs showing both original rocker panels.
• Close-up images of the front and rear ends of each side sill.
• Underside photographs showing the intended fixing area.
• Vehicle year, sales market, G22/G23 body code and trim package.
• VIN or relevant VIN characters when the buyer is permitted to provide them.
• Details of M Sport, repaired or previously modified body components.

BMW identifies G22 as the two-door 4 Series Coupe and G23 as the corresponding Convertible. Buyers can review BMW’s official information for the G22 BMW 4 Series Coupe and G23 BMW 4 Series Convertible. These references identify the vehicle families but do not confirm rocker-panel compatibility.

Add-On Installation Guidance

Professional installation is recommended. Before applying adhesive, drilling or using fasteners, dry-fit both G22 Side Skirts and verify their front/rear orientation, door clearance, wheel clearance and alignment along the factory rocker area. The exact fixing method can vary by application and order specification.

Tape, promoter, screws, brackets or other hardware should not be assumed to be included unless specifically listed in the confirmed quotation and packing list. Installation surfaces must be clean, dry and free from wax, silicone and oil. Carbon parts should never be forced into position; uneven contact or misalignment requires the installer to stop and recheck fitment.

After installation, confirm secure attachment along the full length and recheck ground and wheel clearance. Local regulations and workshop procedures remain the responsibility of the buyer and installer.

B2B Advantages for Aftermarket Buyers

Clear Product Positioning

Distributors can market these BMW 4 Series side skirts using verifiable attributes: prepreg dry carbon, autoclave molding, a paired add-on design, raised fins and multiple weave options. We do not make unsupported downforce, handling or fuel-economy claims; any performance statement should be supported by defined vehicle testing.

OEM, ODM and Private-Label Development

Customization can include 3K/12K/18K weave programs, gloss or matte treatment, logo, graphics, protective film, labels, instruction cards and branded cartons. OEM and ODM projects can be reviewed using target samples, drawings, vehicle references and written acceptance standards. Minimum quantity, sample cost, tooling requirements and lead time depend on the requested scope.

Batch Inspection and Shipping Protection

Commercial inspection points may include left/right pairing, overall length, fin alignment, weave direction, gloss consistency, pinholes, edge finishing, mounting areas, labels and carton condition. Because G22 Side Skirts are long parts with projecting ends, internal supports and surface protection are important during storage and international transportation.

Care and Related G22 Carbon Parts

Support the full length during unpacking and installation. Clean the surface using a microfiber cloth and pH-neutral automotive product; avoid aggressive solvents and abrasive pads. Buyers building a coordinated package can combine these extensions with the G22 dry carbon front lip and G22 dry carbon mirror caps, or browse the carbon fiber side skirts category.
