Porsche 718 (982, 2016+) Prepreg Dry Carbon Fiber Rear Bumper Add-on

Engineered for Porsche 718 Cayman and Boxster (982 chassis, 2016+) owners, this Prepreg (Dry) Carbon Fiber Rear Bumper Add-on brings track-grade carbon aggression to the rear lower section while complementing the car's mid-engine aero balance. Manufactured in Europe to OEM-fit tolerances and quality-controlled by BYC Performance, this Porsche 718 carbon rear bumper add-on bolts directly to factory mounting points — no cutting or modification required.

The 982-generation 718 family represents the purest expression of Porsche's mid-engine philosophy. From the 2.0L and 2.5L flat-4 turbos up to the 4.0L flat-6 naturally-aspirated unit in the GTS 4.0, Spyder, GT4 and GT4 RS (500 hp), the 718 combines motorsport DNA with daily usability. This dry carbon rear bumper add-on reinforces that identity with an aggressive lower-diffuser line. Autoclave-cured prepreg carbon is noticeably lighter than wet-lay carbon parts, offers very high strength for its weight and delivers outstanding UV resistance.

Key Features

• Prepreg (Dry) Carbon Technology: Pre-impregnated plies autoclave-cured under high heat and pressure; a more consistent weave, homogeneous resin.
• Mid-Engine Aero Line: Aggressive diffuser profile matched to the 718 Cayman and Boxster rear bumper geometry.
• Lightweight: Noticeably lighter than the OEM plastic part; supports mid-engine balance.
• 2x2 Twill Carbon Weave: Authentic carbon pattern under high-gloss UV-protective clear coat.
• Direct OEM Fit: Plug & play on factory 982 rear bumper mounting points.
• UV & Chemical Protection: Long-life clear coat resists fading, cracking and exhaust heat.
• Race-Grade Strength: Very high strength for its weight.

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

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

• Autoclave-cured 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
