The legality of the RB8 would become an ongoing theme as the 2012 season progressed. Before the Monaco Grand Prix, several teams complained over the legality of a slot in the rear floor of the RB8. However, Red Bull dismissed claims and pointed out that the hole was within the regulations, as the part in question has been introduced at the Bahrain Grand Prix and had subsequently passed every scrutineering session. Nevertheless, the FIA passed regulation changes before the Canadian Grand Prix that outlawed the use of a hole in the floor, forcing the team to change its design.
