McLaren 540C/570S (2015-2020) Prepreg Dry Carbon Fiber SN Spoiler

Engineered for McLaren 540C/570S Sports Series owners (2015-2020), this Prepreg Dry Carbon Fiber SN Spoiler delivers aggressive rear-deck character and downforce contribution at speed. Made to factory-spec mounting tolerances by leading manufacturers around the world and quality-controlled by BYC Performance, this McLaren 540C SN carbon spoiler bolts directly to OEM mounting points.

Matched to the high-speed character of the 540C/570S 3.8L V8 twin-turbo M838TE engine (540C 533 hp, 570S 562 hp), the aggressive SN-style spoiler is both an aesthetic and aerodynamic upgrade. Autoclave-cured prepreg carbon delivers superior heat, UV and mechanical resistance.

Key Features

  • Prepreg (Dry) Carbon Technology: Autoclave-cured under high heat and pressure.
  • SN-Style Aero: Aggressive spoiler profile tailored to Sports Series rear deck.
  • Downforce Contribution: Adds downforce on rear axle at high speeds.
  • High Strength: Very high strength for its weight.
  • 2x2 Twill Carbon Weave: Authentic pattern under UV-protective clear coat.
  • Direct OEM Fit: Bolts to factory 540C/570S rear-deck mounting points.
