Ferrari 488 GTB / Spider | Prepreg Dry Carbon Fiber CP Rear Diffuser

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

Engineered for Ferrari 488 GTB/Spider (488 GTB Coupé and 488 Spider, 2015-2019) owners, this Prepreg Dry Carbon Fiber CP Rear Diffuser transforms the rear of your supercar with track-grade aggression and aerodynamic gains. Made to factory-spec mounting tolerances by leading manufacturers around the world and quality-controlled by BYC Performance, this Ferrari 488 carbon rear diffuser bolts directly to OEM mounting points, no cutting, no drilling, no modification required.

If you're building a serious Ferrari 488 tuning project and need a part that exceeds the factory plastic diffuser in both performance and finish, this autoclave-cured prepreg carbon fiber is noticeably lighter than wet-lay carbon parts and offers superior UV resistance. Engineered to match the 488 GTB's 661 hp 3.9L V8 twin-turbo F154 CB engine motorsport DNA, this aggressive CP geometry is the ideal upgrade for both track and street.

Key Features

• Prepreg Dry Carbon Technology: Pre-impregnated carbon plies autoclave-cured under high heat and pressure, homogeneous resin, a more consistent weave.
• CP Styling: Catalog-internal CP code, a distinct design line for the 488 family.
• Aerodynamic Performance: Optimized diffuser channels accelerate underbody airflow and generate downforce at high speeds.
• Race-Grade Strength: Carbon fiber offers very high strength for its weight.
• Lightweight: Noticeably lighter than the factory plastic part.
• 2x2 Twill Carbon Weave: Authentic carbon fiber pattern under high-gloss UV-protective clear coat.
• Direct OEM Fit: Plug & play on factory 488 GTB/Spider mounting points.

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

Most aftermarket carbon parts use wet lay-up: hand-applied resin 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

Installation Notes

Professional installation recommended:

1. Raise the vehicle and remove rear bumper underbody screws.
2. Detach the OEM plastic diffuser from clips and bolts.
3. Test-fit the carbon diffuser for alignment.
4. Secure with supplied hardware to the manufacturer's recommended torque.
5. Verify exhaust tips are centered in diffuser cutouts.

Care & Maintenance

Wash with pH-neutral car shampoo. Apply carbon-safe sealant every 6 months. Keep pressure washer at least 30 cm from surface.
