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.
