Bimmer Plug mirror caps are manufactured from genuine carbon fiber — not carbon-look ABS plastic or vinyl-wrapped covers. The 2x2 twill weave is laid up and cured to produce a rigid, lightweight shell that delivers authentic motorsport aesthetics alongside real structural integrity. Every cap undergoes a visual inspection for weave uniformity, ensuring the pattern is consistent, aligned, and free from voids or surface irregularities before it leaves production. This is the standard BMW M enthusiasts demand — and the standard Bimmer Plug holds every part to.

The carbon fiber surface on each mirror cap is protected under a multi-layer, high-gloss clear coat formulated with UV inhibitors. This coating shields the carbon weave from the primary causes of aftermarket carbon degradation — sun yellowing, surface oxidation, and micro-abrasion from road debris and car washes. The result is a finish that retains its depth, gloss, and clarity across seasons of daily driving and exposure. Unlike budget carbon alternatives that yellow within a year, Bimmer Plug caps are finished to a standard that holds up under real-world conditions for the long term.
