McLaren 720S (2017-2023) Prepreg Dry Carbon Fiber RY Spoiler

Engineered for McLaren 720S Coupé (2017-2023) owners, this Prepreg Dry Carbon Fiber RY Spoiler adds track-grade aggression and visual downforce to your 720S rear deck in the RY design language. Manufactured in Europe to factory-spec tolerances by BYC Performance, it bolts directly to OEM mounting points.

The 720S's 4.0L twin-turbo V8 M840T (710 hp / 720 PS metric) and carbon MonoCage II monocoque deliver Super Series performance, and the RY spoiler completes the look with clean carbon surfaces and an aerodynamic profile. Coordinates with the rest of the RY aero set (side skirts, front hood, front lip).

Key Features

• Prepreg (Dry) Carbon Technology: Autoclave-cured homogeneous resin, a more consistent weave.
• RY Design: Coordinated design with the RY carbon aero set (side skirts, front hood, front lip).
• Aerodynamic Contribution: Increases rear-axle downforce at speed.
• High Strength: Very high strength for its weight.
• 2x2 Twill Carbon Weave: Under high-gloss UV-protective clear coat.
• Direct OEM Fit: Factory 720S Coupé rear deck mounting points.
• UV & Chemical Protection: Long-life clear coat.

Prepreg (Dry) Carbon vs. Wet 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
