The FIA aims to simplify the underfloor plank on Formula 1 machinery and has set its sights on standardising the
In October, Lewis Hamilton and Charles Leclerc were disqualified from the United States Grand Prix for exceeding the floor plank wear limit. Only four drivers had their planks checked after the race, but Hamilton claimed that many more would have been caught if all cars were checked. The plank is meant to restrict the minimum ride height of the car and ensure safety. The regulations currently state that the plank must be 10mm thick with a tolerance of +/- 0.2mm. Lower ride heights can improve performance by producing higher levels of downforce, but it also comes with risks of bottoming out and aerodynamic disruptions. The FIA has considered adding the floor plank as a standard part, but the proposal was rejected by the teams. However, for the 2026 regulations, they plan to simplify this area.
