BMW M3 G80 / M4 G82 Prepreg Dry Carbon Fiber Mirror Cap Set

Engineered for BMW M3 G80 and BMW M4 G82 owners, this Prepreg Dry Carbon Fiber Mirror Cap Set brings M Performance / CSL styling to your side mirrors. Autoclave-manufactured in Europe and quality-controlled by BYC Performance, this G80 / G82 carbon mirror cap set replaces the factory mirror caps directly — no cutting, no drilling, no adhesive prep required beyond the OEM clip system.

Designed to match the aggressive lines of the new-generation S58-powered M family (M3 Sedan G80 473-543 hp, M4 Coupé G82 473-543 hp, M4 Convertible G83 503 hp), this mirror cap snaps onto both M3 G80 and M4 G82 mirror housings without modification. Prepreg carbon fiber cured under high heat and pressure in an autoclave is noticeably lighter than wet-lay carbon and significantly more UV-resistant.

Key Features

• Prepreg (Dry) Carbon Technology: Pre-impregnated carbon plies cured in an autoclave under high pressure; a more consistent weave, homogeneous resin.
• M Performance / CSL Styling: Direct carbon version of the OEM MP carbon mirror caps — deeper gloss and lighter build.
• 2x2 Twill Carbon Weave: Authentic carbon fiber pattern under a high-gloss UV-protective clear coat.
• Direct OEM Fit: Snaps onto M3 G80 Sedan, M3 Touring G81, M4 G82 Coupé, and M4 G83 Convertible mirror housings.
• Left + Right Pair: Driver + passenger side, matched weave and color.
• Lightweight: Noticeably lighter than the factory plastic caps.
• UV & Chemical Protection: Long-life clear coat resists fading, cracking, fuel splash, and road tar.

Prepreg (Dry) Carbon vs. Wet Carbon — Which Is Better?

Most aftermarket carbon parts are made using wet lay-up, where resin is applied by hand and cured at room temperature — leaving air voids and inconsistent weight. Prepreg (dry) carbon:

• Cured in an autoclave under high heat and pressure → a more consistent weave
• Controlled resin ratio → lighter and stronger
• The production method widely chosen in motorsport
• Minimal UV fading over years of use

4. Align the new carbon cap to the clip points and press firmly until each clip seats audibly.
5. Return the mirror to its normal position and verify the cap is fully seated.

Care & Maintenance
