Ferrari Roma (2019+) Prepreg Dry Carbon Fiber Rear Diffuser

Engineered for Ferrari Roma (2019+) owners, this Prepreg Dry Carbon Fiber Rear Diffuser brings track-grade detail and function to La Nuova Dolce Vita's elegant rear. Autoclave-cured in Europe and quality-controlled by BYC Performance, this Ferrari Roma carbon rear diffuser bolts directly to OEM mounting points — no cutting, no drilling, no modification.

The Roma uses a 3.9L V8 twin-turbo F154 BH (612 hp, 760 Nm) in a front-mid engine 2+2 GT layout — a fundamentally different chassis from mid-engine cars like the 488, F8, or SF90. This dry carbon rear diffuser is built specifically for the Roma's bumper geometry and is NOT compatible with other Ferrari models. Autoclave-cured prepreg technology delivers a noticeably lighter part than wet-lay carbon, superior structural integrity, and outstanding UV resistance.

Key Features

• Prepreg (Dry) Carbon Technology: Pre-impregnated carbon plies cured in an autoclave under high heat and pressure; homogeneous resin distribution, a more consistent weave.
• Roma-Specific Geometry: Diffuser lines tailored to the front-mid engine GT 2+2 platform with aggression that respects the Dolce Vita design language.
• Race-Grade Strength: Very high strength for its weight. Resists stone chips and light contact.
• Aerodynamic Performance: Optimized channels accelerate underbody airflow and add downforce at high speed.
• 2x2 Twill Carbon Weave: Authentic pattern under high-gloss UV-protective clear coat.
• Direct OEM Fit: Plug & play on factory Ferrari Roma (2019+) mounting points.
• UV & Chemical Protection: Long-life clear coat resists fading, cracking, and fuel/road tar splash.

Prepreg (Dry) Carbon vs. Wet Carbon

Most aftermarket carbon parts use wet lay-up — resin applied by hand, room-temperature cure, with voids and inconsistent weight. Prepreg (dry) carbon:

• Cured under high heat and pressure in an autoclave → 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

Vehicle Fitment

This Ferrari Roma rear diffuser fits:

• Ferrari Roma Coupé (2019, 2020, 2021, 2022, 2023, 2024) — 3.9L V8 twin-turbo (612 hp)
• Ferrari Roma Spider (2023+) — likely compatible since Spider shares much of the rear deck/bumper geometry with Coupé; verify with VIN before installation.

Important notes:

• NOT compatible with Ferrari 488 GTB/Spider, F8 Tributo/Spider, 296 GTB/GTS, or SF90 Stradale/Spider. The Roma uses a front-mid engine 2+2 GT chassis; those are mid-engine platforms.
• NOT compatible with Ferrari Portofino or Portofino M. They share the engine family but use different rear bumper and diffuser geometry.
