Every spoiler begins with real 2x2 twill weave carbon fiber — not ABS plastic with carbon film applied. The carbon layers are bonded under pressure for structural rigidity and weave consistency. Each unit is individually inspected before shipping to verify carbon weave alignment, clear coat uniformity, and mounting hardware completeness. BMW enthusiasts can identify the difference between genuine carbon fiber and carbon-look plastics immediately — which is why Bimmer Plug uses only authentic carbon fiber across all carbon exterior products.

The carbon fiber surface of every CS Style Trunk Spoiler is sealed with a multi-stage UV-resistant clear coat applied in controlled conditions. This protective layer prevents the yellowing, hazing, and surface oxidation that degrades unprotected carbon fiber components over time. The gloss clear coat maintains the visual depth of the carbon weave through regular washing, seasonal temperature changes, and continuous sun exposure. The result is a finish that holds its appearance across years of daily driving — not just for the first season after installation.

The CS Style Carbon Fiber Trunk Spoiler is engineered to OEM mounting specifications for the BMW F80 M3 and F30 3 Series. Mounting points align with factory trunk lid hardware to eliminate gaps, misalignment, or panel flex during installation. Every spoiler ships with all required mounting hardware included.
