McLaren 720S (2017-2023) Prepreg Dry Carbon Fiber Rear Bumper Add-on

Engineered for McLaren 720S Coupé and Spider (2017-2023) owners, this Prepreg Dry Carbon Fiber Rear Bumper Add-on adds racing-grade carbon texture and an aggressive silhouette to the rear diffuser/bumper transition. Manufactured in Europe and quality-controlled by BYC Performance, this part bolts directly to OEM mounting points.

The 720S's 4.0L twin-turbo V8 M840T engine (710 hp, 0-100 km/h in 2.9 s) and carbon MonoCage II monocoque deliver Super Series performance — and this dry carbon rear bumper add-on visually matches that pedigree with autoclave-cured prepreg carbon for lightweight strength.

Key Features

• Prepreg (Dry) Carbon Technology: Autoclave-cured, a more consistent weave.
• Aggressive Design: Adds fin detail at the diffuser/bumper transition.
• High Strength: Very high strength for its weight.
• Aerodynamic Contribution: Reduces underbody turbulence at speed.
• 2x2 Twill Carbon Weave: Authentic carbon under high-gloss UV-protective clear coat.
• Direct OEM Fit: Factory 720S rear bumper mounting points.
• UV & Chemical Protection: Long-life clear coat.

Prepreg (Dry) Carbon vs. Wet Carbon

Most aftermarket parts use wet lay-up with hand-applied resin and room-temperature curing. 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
