FIA tells top teams to change 'splitters' - reports

Apr.2 (GMM) F1's governing body has warned three top teams to make changes to their cars ahead of the next race in China, it has emerged.

Italian reports, including in the pages of Italiaracing and Omnicorse, claim the FIA has reacted after scrutineers flagged controversial solutions in the area of the underbody presented in Malaysia by Red Bull, Lotus and Mercedes.

The reports say the cars' 'splitters' are too flexible, with the teams told to make changes for Shanghai to avoid sanction.
