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. Imported from leading manufacturers around the world 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

Installation Notes

  1. Lift the vehicle; clean the rear bumper lower area.
  2. Dry-fit the carbon add-on.
  3. Secure with supplied 3M VHB tape or hardware to the manufacturer's recommended torque.
  4. Verify parking sensor cutouts.
  5. Final inspection.

Care & Maintenance

Use pH-neutral car shampoo. Apply carbon sealant every 6 months. Keep pressure washer 30 cm from surface.
