McLaren 600LT (2018-2020) Prepreg Dry Carbon Fiber Spoiler

Engineered for McLaren 600LT Sports Series Longtail (2018-2020) owners, this motorsport-derived Prepreg Dry Carbon Fiber Spoiler brings the aggressive factory Longtail character and high-speed downforce to the 600LT's extended rear deck. Made to factory-spec mounting tolerances by leading manufacturers around the world and quality-controlled by BYC Performance, this McLaren 600LT carbon spoiler bolts directly to OEM mounting points.

The fixed spoiler geometry aligns with the 600LT's 3.8L V8 twin-turbo (600 hp) engine and motorsport-derived Longtail aero philosophy, delivering both visual and aerodynamic upgrades.

Key Features

  • Prepreg (Dry) Carbon Technology: Autoclave-cured under high heat and pressure.
  • Longtail Fixed Spoiler: 600LT motorsport-derived fixed-spoiler philosophy.
  • Downforce Contribution: Adds rear-axle downforce at high speeds.
  • High Strength: Very high strength for its weight.
  • 2x2 Twill Carbon Weave: Glossy pattern under UV-protective clear coat.
  • Direct OEM Fit: Bolts to factory 600LT extended rear deck mounting points.

  3. Align and bond the spoiler.
