Side skirts are one of the most visually impactful body modifications available for the G20 platform. They extend the visual width of the lower body, reduce apparent ride height, and create a visual bridge between the front and rear bumper lines. On the G20 and G28 LCI, these JC Sportline skirts accomplish all of that using genuine dry pre-preg carbon fiber rather than the ABS or fibreglass alternatives that dominate this price category.
The distinction between dry carbon (pre-preg) and wet-layup carbon is significant. Pre-preg carbon uses resin-impregnated fibre sheets that are vacuum-bagged and cured under pressure in an autoclave. This process produces a higher fibre-to-resin ratio, a denser, lighter structure, and a more consistent 3K twill weave surface compared to hand-laid alternatives. The process used here follows a 3D design / CNC milling / autoclave curing sequence, with the panel geometry derived from precision body scan data of the G20 platform.
The surface is finished in high-gloss epoxy clearcoat, exposing the full 3K twill weave pattern beneath. The result is the deep, layered carbon appearance that distinguishes properly cured autoclave parts from cheaper printed-film or wet-laid alternatives.
Dimensions and fitment:
- Length: 169.6 cm (66.77 inches) per side
- Height: 9.2 cm (3.62 inches)
- Overall package dimensions: 125 x 20 x 15 cm
- Installation: add-on fit using adhesive glue tape and screws, both included
- No drilling required
The geometry is designed to OEM panel specifications for the G20 and G28 LCI body. No modification to the factory sill or bumper is required for installation. Professional fitment is recommended, and minor adjustments during installation are normal for carbon bodywork.

Important purchasing notes: carbon fibre is a hand-finished material. Minor surface variations in weave pattern, small micro-bubbles in clearcoat, and slight texture inconsistencies are inherent to the material and are not considered defects. Each panel is gel-coated and individually inspected before shipping. Returns are accepted within 7 days of delivery on uninstalled items in original packaging. Shipping damage must be reported to the carrier and seller within 24 hours of receipt. There are no returns on painted or installed products.
