Although some aero devices were deemed legal in Bahrain, the FIA scrutineers did take a different view of some teams starter holes. This hole is allowed with in the rule to be in the diffuser in order to alow the starter mechanism to be inserted. Normally this is a simple round hole, but some teams have expanded the hole into a much wider ellipse shape. This effectively makes the starter hole an extra slot to alow the diffuser to be steeper and create more downforce. The Scrutineers have asked for these designs to be changed before the Australian GP.
