2009 regulation changes - rear diffuser 30 January 2009

As part of the package of aero changes designed to reduce downforce for 2009, the diffuser has undergone quite complex modifications. Moves to create a more standardised shape have removed the difference in height between the central and two outer sections and all three channels are now taller - 175mm rather than 125mm. In addition, the diffuser has been moved rearwards, with its trailing edge now 350 mm behind the rear axle - previously, it was level with the rear axle.
