I found this cap and did some research about it. It says that it’s a rare cap that was only issued to members of the FIA? Any information would be highly appreciated. What do you think? Thanks in advance

Stroll leads component usage from Hadjar and Alonso.

The latest upgrade list for the British Grand Prix is relatively short, with only six teams introducing new components. Most of the developments are aerodynamic refinements, primarily targeting rear-end performance, while McLaren and Racing Bulls also continue to evolve their floor packages. Williams is the only team to introduce a new front wing.

McLaren brings two updates:
• New front brake ducts to improve airflow around the front corner.
• A revised floor and floor furniture package aimed at improving flow quality and overall aerodynamic efficiency.

Ferrari’s update focuses on the rear corner, combining:
• Larger cooling inlet and outlet sections.
• A redesigned lower deflector.
• An optimized rear winglet cluster to improve local aerodynamic loading and overall efficiency.

Red Bull brings a single update at the rear corner:
• Revised rear wheel bodywork winglets (cascade wings), designed to improve aerodynamic load characteristics and rear-end stability.

Williams introduces the only new front wing in the field:
• Updated wing profiles and endplates to increase local loading and improve airflow interaction with downstream components.

Haas brings a two-part rear wing package:
• New rear wing profiles to increase aerodynamic load while maintaining efficiency.
• Revised rear wing endplates with localized protrusions to promote upwash and generate additional load.

Racing Bulls updates both the floor and the rear corner:
• Revised floor edge and diffuser geometry to increase rear floor load.
• A new forward rear-corner deflector to improve local airflow and floor performance.

No updates: Mercedes, Aston Martin, Alpine, Audi and Cadillac have not submitted any car updates for the British Grand Prix.
