Teams pass new flexi-tests

Amid suspicions from rival teams that Red Bull Racing and Ferrari were somehow exploiting the regulations - through either flexible bodywork or a bendy-floor - to get their front wings lower to the ground, the FIA introduced a raft of new rules and tests for the last two races.

From Belgium, the FIA toughened up the front wing deflection tests - while from this weekend revised tests took place on the floor, plus new rules specified how the skid block could be made up.

Every team is believed to have had to make modifications to their floors, but everyone claimed it had not affected their performance.

The FIA tested the McLaren car with the new tests after Friday practice, while the cars of Jenson Button (McLaren), Mark Webber (Red Bull Racing) and Fernando Alonso were all examined after qualifying on Saturday.

The FIA reported the cars were found to be in conformity with the regulations - and the matter has not drawn much comment from teams up and down the grid.
