FIA Approval: The Gold Standard for Historic Motorsport

For any component used in competitive motorsport, especially in categories governed by strict historical regulations, FIA approval is paramount. The Fédération Internationale de l'Automobile (FIA) sets global standards for motorsport, covering everything from safety to technical specifications. In historic racing, FIA approval ensures that parts meet specific criteria for period correctness, safety, and performance, preventing unfair advantages and maintaining the integrity of the sport.

When a component is FIA approved, it means it has undergone rigorous scrutiny to confirm it complies with the regulations pertinent to its class and era. This can involve detailed examination of materials, manufacturing processes, dimensions, and performance characteristics. For reproduction parts, this often means demonstrating that they are built precisely to original specifications and offer comparable, if not superior, performance and reliability to their historical counterparts, while still fitting within the spirit of the regulations.

BG Developments and the Revival of Girling Calipers

This is where specialists like BG Developments play a crucial role. Recognising the demand for authentic, high-performance braking solutions for historic race cars, they have invested heavily in recreating Girling calipers to the highest possible standards.
