McLaren 650s rear bumper carbon 11A7741CP.02

the part number 11A7741CP.02 refers to a high-value component of the McLaren 650S rear assembly—specifically the Visible Carbon Fiber Rear Bumper/Diffuser section.

In the McLaren 650S, the rear bumper is a multi-piece assembly. The “CP” in the part number typically denotes a Carbon Program part, meaning this is the high-gloss, weave-exposed version rather than the standard “Dark Palladium” painted composite.

1. Technical Specifications

• Material: Pre-preg Carbon Fiber (Autoclave-cured).

• Finish: High-Gloss UV-resistant clear coat.

• Fitment: This part is specific to the 650S (Coupe and Spider). While the 650S shares some DNA with the 12C, the rear aero and bumper profiles are different; this part will not be a direct bolt-on for a 12C without significant modifications to the exhaust surrounds and mesh.

• Weight: Approximately 3.2 kg, offering a slight weight saving over the non-carbon variant.
