New regulation - plank length 11 September 2010
At Monza, the FIA have introduced a new rule which means it is now prohibited to run a section of plank less than 1000mm in length. The plank is a hard wooden strip (also known as a skid block) fitted down the middle of a car's underside (see red arrow). This regulation is designed to prevent teams from running 'articulated' planks that are made up of multiple pieces.
