The structure Ferrari mounted to the Halo of its F1 car at the Spanish Grand Prix to incorporate rear-view mirrors has been banned.
Ferrari unveiled the most creative use of the Halo so far in Barcelona, with mirrors and an extra winglet either side of the cockpit safety device. The team said the structure was made to aid visibility for the driver, which was the condition in the regulations allowing for such designs.
Ferrari felt it had done enough to seek clarification on what was acceptable ahead of the Barcelona race.
