Ferrari 488 GTB/Spider (2015-2019) Prepreg Dry Carbon Fiber SN Rear Diffuser

Engineered for Ferrari 488 GTB and 488 Spider (2015-2019) owners, this Prepreg Dry Carbon Fiber SN Rear Diffuser is an aggressive alternative offering a different design language from the CP variant. Manufactured in Europe and quality-controlled by BYC Performance, this Ferrari 488 carbon rear diffuser bolts directly to OEM mounting points.

The SN styling features different channel geometry and fin placement than the CP. Autoclave-cured prepreg carbon is noticeably lighter than wet-lay carbon and offers superior strength. Adds downforce to the 488 GTB's 661 hp F154 CB rear aerodynamics.

Key Features

• Prepreg Dry Carbon Technology: Autoclave-cured under high heat and pressure.
• SN Styling: Catalog-internal SN code, distinct design language vs CP.
• Aerodynamic Performance: Optimized diffuser channels generate downforce.
• Lightweight: Noticeably lighter than OEM plastic.
• 2x2 Twill Carbon Weave.
• Direct OEM Fit: Plug & play.
• UV & Chemical Protection.

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

Most aftermarket carbon parts use wet lay-up. 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
