The FIA have confirmed that they will look into suspension systems at the Barcelona pre-season test, determining what is legal and what is not.
However, Auto Motor und Sport has reported Formula 1's governing body will make a round to all teams after today's test, inspecting the suspension systems before deeming their legality.
"The clarification is a basis for the stewards in disputes," an FIA source is quoted as saying. "Whether a suspension is in conflict with that clarification will then be (decided) on a case by case basis."
"Everyone can use what they want," said FIA race director Charlie Whiting. "But it would be foolish to test something which cannot be used in Melbourne."
"The teams asked us if we are satisfied with the function of certain components and we answered yes or no. Now they have to prove it to us."
