Lotus Renault R31 – More diffuser revisions in Australia


  The diffuser was again revised in Australia despite the latest upgrade at Barcelona test ,  having now a new slotted tab under the crash structure to let air bleed through .

Lotus Renault R31 – updated diffuser before season starts

Barcelona test on March

Lastly the tab under the rear structure lost its cut  ( all changes in yellow ) .
