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. Manufactured in Europe to factory-spec mounting tolerances 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.

Prepreg (Dry) vs. Wet Carbon

Prepreg carbon is autoclave-cured under high heat & pressure, a more consistent weave, a controlled resin ratio — the production method widely chosen in motorsport.
