In F1 the T-tray is the front part of the floor of the car, under the driver's legs. It forms a splitter and is one of the most important aerodynamic parts of the car, as it affects the air flow under the car and around the sidepods.
Because it runs close to the ground at the front of the car, the T-tray is susceptible to damage from debris or kerb impact. It is usually designed as a replaceable component so that damage can be easily repaired.
