2011 rule changes - rear-view mirror placement 03 February 2011
Ahead of last year's Spanish Grand Prix, the teams agreed to change the placement of rear-view mirrors for safety reasons and this has now been set in stone in the regulations. Previously, teams had started to position mirrors to boost aero efficiency, with the driver's rearward vision becoming an increasingly secondary consideration. Mirrors must now be 'inboard', where they can be of most benefit to the drivers.
FIA Technical Regulation
14.3.3 - All parts of the rear view mirrors, including their housings and mountings, must be situated between 250mm and 500mm from the car centre line and between 550mm and 750mm from the rear edge of the cockpit entry template.
