The Plank<\/strong> (or skid block) is the rigid laminated strip made of composite (phenolic) material fitted to the central underside of the F1 car. Introduced in 1994 as a safety measure to limit ground effect and speeds, it is now the barometer for extreme aerodynamic set-ups.<\/p>\n\n\n\n

The rule is absolute: the plank, which initially measures 10 mm<\/strong> in thickness, cannot fall below 9 mm<\/strong> at the control points designated by the FIA. This 1 mm wear tolerance<\/strong> is the fine line between legality and disqualification.<\/p>\n\n\n\n

The recent case of McLaren<\/strong>, disqualified for excessive wear of the plank, has put a spotlight back on this component. Exceeding the limit, even by fractions of a millimeter, is proof that the car was run at a more aggressive ride height than permitted, obtaining a direct advantage in terms of downforce<\/strong> generated by the floor.<\/p>\n\n\n\n
