McLaren 600LT (2018-2020) Prepreg Dry Carbon Fiber Rear Hood / Engine Cover

Engineered specifically for the McLaren 600LT Sports Series Longtail (2018-2020), this motorsport-derived Prepreg Dry Carbon Fiber Rear Hood replaces the extended Longtail rear deck panel with a track-grade carbon piece. Manufactured in Europe to factory-spec mounting tolerances and quality-controlled by BYC Performance, this McLaren 600LT carbon rear hood bolts directly to OEM mounting points.

Engineered around the 600LT's 3.8L V8 twin-turbo (600 hp) top-exit exhaust system and extended Longtail rear deck geometry, this rear hood includes optimized vent slots for engine bay heat management.

Key Features

• Prepreg (Dry) Carbon Technology: Autoclave-cured under high heat and pressure, a more consistent weave.
• Longtail-Specific: Tailored to the 600LT's extended rear deck + top-exit exhaust geometry.
• Weight Reduction: Noticeably lighter than factory aluminum/composite hood.
• Heat Management: Slot/vent geometry optimized for top-exit exhaust heat extraction.
• 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 hinge + latch + lifter 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.

Vehicle Fitment

• McLaren 600LT Coupé (2018-2020) — 3.8L V8 twin-turbo, 600 hp, Longtail aero, top-exit exhaust

Important notes:

• NOT compatible with the 600LT Spider — Spider's folding hardtop changes rear deck mechanics.
• NOT compatible with McLaren 540C/570S. The 540C/570S have different non-Longtail rear deck geometry.
• NOT compatible with McLaren 720S (different chassis platform - MonoCage II).
• NOT compatible with McLaren 765LT (Super Series Longtail, different platform).
