BMW M3 F80 / M4 F82 Prepreg Dry Carbon Fiber Rear Bumper

Designed for BMW M3 F80 and M4 F82 owners, this full Prepreg Dry Carbon Fiber Rear Bumper is a complete replacement panel that is far lighter, more aggressive, and built to racing standards compared to the factory plastic bumper. Autoclave-cured in Europe and quality-controlled by BYC Performance, this BMW F80 / F82 carbon rear bumper bolts to OEM mounting points — no cutting or bonding required.

Engineered to match the aggressive character of the S55B30T0-powered M3/M4 family (425 hp standard, 444 hp Competition, 460 hp CS, 493 hp GTS), this dry carbon rear bumper delivers both a track-day look and daily-driver durability. Park sensor and rear-view camera cutouts are in OEM positions.

Key Features

• Prepreg (Dry) Carbon Technology: Autoclave-cured under high heat and pressure; a more consistent weave, controlled resin ratio.
• Full Rear Bumper: Not just a diffuser — a complete bumper replacement with aggressive track-spec styling.
• Noticeably Lighter: Significant weight savings vs OEM plastic bumper.
• OEM Sensor / Camera Cutouts: Original PDC sensors and reverse camera transfer directly.
• 2x2 Twill Carbon Weave: Glossy black weave under high-gloss UV-protective clear coat.
• Race-Grade Strength: Carbon fiber offers very high strength for its weight.
• Plug & Play Fit: OEM brackets and clip points are preserved.

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
• A controlled resin ratio → lighter and stronger
• The production method widely chosen in motorsport
• Minimal UV fading over years of use
