McLaren 720S | Prepreg Dry Carbon Fiber 765LT Body Kit

McLaren 720S (2017-2023) Prepreg Dry Carbon Fiber 765LT Body Kit

Engineered for McLaren 720S Coupé (2017-2023) owners, this Prepreg Dry Carbon Fiber 765LT Body Kit transforms your 720S with the full factory 765LT Longtail aero look. Made to factory-spec tolerances by leading manufacturers around the world and quality-controlled by BYC Performance, this complete kit bolts directly to OEM mounting points: no cutting, drilling, or permanent modification.

If you're building a serious McLaren 720S tuning project and want McLaren Longtail DNA aggression without compromising fit, this dry carbon 765LT body kit is built for you. The 720S's 4.0L twin-turbo V8 M840T (710 hp / 720 PS metric) and carbon MonoCage II monocoque are visually completed by the factory 765LT aero language (755 hp / 765 PS metric Longtail Super Series limited). Autoclave-cured prepreg carbon delivers a noticeably lighter build than wet-lay carbon, superior structural integrity, and outstanding UV resistance.

Key Features

• Prepreg (Dry) Carbon Technology: Pre-impregnated plies cured in autoclave under high heat and pressure, a more consistent weave, balanced resin distribution.
• Complete 765LT Aero Conversion Kit: Front bumper, front splitter, side skirts, rear bumper, and Longtail spoiler. Transforms 720S into 765LT visual spec.
• High Strength: Carbon fiber offers very high strength for its weight.
• Longtail Aerodynamics: Extended rear deck profile, aggressive front splitter, and enlarged diffuser channels generate downforce at speed.
• 2x2 Twill Carbon Weave: Authentic carbon pattern under a high-gloss UV-protective clear coat.
• Direct OEM Fit: Plug & play on factory 720S Coupé mounting points, no cutting, drilling, or bonding required.
• 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 voids and inconsistent weight. Prepreg (dry) carbon:

• Cured in 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

Installation Notes

McLaren 720S body kit installation requires professional fitment. General procedure:

1. Lift the vehicle and remove front and rear bumpers from OEM mounting points.
2. Detach factory side skirts.
3. Test-fit each carbon piece dry to verify panel gaps.
4. Secure with supplied hardware + clips to the manufacturer's recommended torque.
5. Route parking sensors / PDC harnesses through the new bumper cutouts.
6. Final torque pass; verify edge gaps.

Care & Maintenance

Wash with pH-neutral car shampoo. Apply carbon-safe sealant every 6 months. Keep pressure washer nozzle at least 30 cm from surface.
