Every CS Style Trunk Spoiler begins with hand-laid 2x2 twill weave carbon fiber sheets, carefully positioned and compressed under controlled curing conditions. This labor-intensive process ensures uniform fiber alignment, consistent resin distribution, and zero voids in the finished part. The result is a structurally sound carbon fiber component that delivers genuine weight reduction and surface integrity — not a carbon-look vinyl wrap or thin veneer over plastic. Each unit is inspected for surface consistency and structural integrity before leaving the production facility.

The carbon fiber surface is finished with a multi-stage UV-stabilized high-gloss clear coat engineered to withstand years of sun exposure, wash cycles, and temperature cycling without yellowing, hazing, or delamination. Standard aftermarket carbon parts frequently exhibit UV degradation within 12-18 months, resulting in a dull, chalky surface. Bimmer Plug's clear coat process provides a durable protective layer that maintains deep gloss depth and preserves the authentic carbon fiber texture — keeping your G80 M3 or G20 3 Series looking sharp season after season.

Every CS Style Carbon Fiber Trunk Spoiler is backed by Bimmer Plug's Manufacturer's Warranty covering defects in materials and workmanship. Each unit is inspected prior to shipment for surface quality, structural integrity, and fitment accuracy against the G80 M3 and G20 3 Series mounting specifications. In the unlikely event of a manufacturing defect, Bimmer Plug's support team is available to assess and resolve your claim directly.
