FIA closes door on diffuser loophole

As reported by ESPNF1 last weekend, several teams will have to make modifications to their diffuser designs ahead of the Australian Grand Prix after a ruling by the FIA clamping down on a loophole.
Discussions between the FIA and four teams - understood to be Force India, McLaren, Mercedes and Renault - took place in Bahrain about the size of starter motor holes in their diffusers which were believed to be too wide. While this was not a technical breach of the rules, the FIA's view was that it was not in accordance with the spirit of them.
As a result of FIA inspections and the meeting, a note has been sent out clarifying the exact dimensions allowed. This will mean the four teams will have to make changes before practice in Melbourne next Friday.
