Ferrari has said that it will now look to make changes to its F60 after the FIA Court of Appeal ruled that the double-decker diffusers used by Brawn GP, Williams and Toyota are legal.
was one of the teams to appeal to the FIA about the controversial part, claiming that the three teams had gone outside the regulations in fitting the diffuser to its cars.
The Court of Appeal's decision follows on from stewards in both Australia and Malaysia rejecting appeals against the part, and Ferrari team principal Stefano Domenicali said that the team would now look into creating a solution for the cars of Kimi Raikkonen and Felipe Massa.
"We are waiting to hear the reasons the ICA rejected the appeal," Domenicali said. "Unfortunately this decision forces us to intervene on fundamental areas of the car's design in order to be able to compete on an equal footing with some of the teams from a point of view of the technical regulations, and that will take time and money.
"We will now double our efforts to get the team back to the highest level of competitivity."
Ferrari has endured a tough start to the year so far, and has yet to score after the opening two races of the campaign.
