McLaren 540C / 570S | Prepreg Dry Carbon Fiber 675LT Body Kit

McLaren 540C/570S (2015-2020) Prepreg Dry Carbon Fiber 675LT Body Kit

Engineered for McLaren 540C/570S Sports Series owners (2015-2020) who want the aggressive aerodynamic character of the factory 675LT trim, this Prepreg Dry Carbon Fiber 675LT Body Kit transforms your supercar with track-grade aero. Made to factory-spec mounting tolerances by leading manufacturers around the world and quality-controlled by BYC Performance, this McLaren 540C/570S carbon body kit bolts directly to OEM mounting points.

If you're building a serious McLaren 540C tuning or 570S modification project and need a complete aero kit that channels the 675LT racing DNA, this dry carbon 675LT body kit is built for you. Autoclave-cured prepreg carbon fiber delivers a noticeably lighter build than wet-lay carbon parts, far superior structural integrity, and outstanding long-term UV resistance. Engineered to match the performance character of the 540C/570S's 3.8L V8 twin-turbo M838TE engine (540C 533 hp, 570S 562 hp), this aggressive 675LT geometry is the ideal aesthetic and functional upgrade for both track and street use.

Kit Contents

• 675LT Front Bumper / Splitter: Extended front splitter with aggressive air intake channels
• 675LT Side Skirts: Lengthened skirts with downforce channels
• 675LT Rear Bumper / Diffuser: Dual large exhaust cutouts and aggressive diffuser fins
• 675LT Rear Spoiler / Airbrake: 675LT-styled fixed spoiler design

Key Features

• Prepreg (Dry) Carbon Technology: Pre-impregnated carbon plies cured in an autoclave under high heat and pressure ensure a more consistent weave and balanced resin distribution.
• 675LT Aero Geometry: Inspired by the McLaren 675LT (2015-2017 limited, 666 hp) factory aerodynamic character. Noticeably lighter than the factory 540C/570S parts.
• High Strength: Carbon fiber offers very high strength for its weight.
• Aerodynamic Performance: Optimized splitter + diffuser + spoiler combination generates downforce at high speeds.
• 2x2 Twill Carbon Weave: Authentic carbon fiber pattern under a high-gloss UV-protective clear coat.
• Direct OEM Fit: Plug & play installation on factory McLaren 540C/570S Coupé mounting points.
• UV & Chemical Protection: Long-life clear coat protects against fading, cracking, fuel splash, and road tar.

Prepreg (Dry) Carbon vs. Wet Carbon: Which Is Better?

Most aftermarket carbon parts are made using wet lay-up, where resin is applied by hand and cured at room temperature, leaving air voids and inconsistent weight. Prepreg (dry) carbon:

• Cured in an autoclave 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 of use

FAQ

Does this fit the actual factory McLaren 675LT?
No. The factory 675LT (2015-2017 limited) already shipped with 675LT aero. This kit is designed to convert 540C/570S into the 675LT visual styling.

Compatible with 570S Spider or 570GT?
No. Spider's folding hardtop and GT's different rear glass make this Coupé-spec kit incompatible.

Compatible with 600LT?
No. The 600LT uses different Longtail aero geometry (extended rear deck, top-exit exhaust). Dedicated 600LT carbon aero is available in our catalog.

Compatible with 720S?
No. The 720S Super Series uses a different chassis platform (MonoCage II).

Will rain damage dry carbon parts?
No. Autoclave-cured prepreg carbon is fully waterproof and weather-resistant.
