I don’t know if these days cars do that but I remember previously the cars used to, after finishing the race the driver slows down and picks up as much rubber as possible. I have heard Radio messages where the driver is also told to do so. Why is it so necessary?
@aish Because this gains the car some extra weight, without having to suffer for it during the race. The teams run the cars very marginally against the weight limit, so this helps to ensure that the car do not fail any weight tests.
@keithcollantine I’ve also heard that they make it to increase the height of the car. Is it true? Or in other words, is there a minimum height for the car and do teams try to make their cars as low as possible?
@aish In dry conditions, no. In conditions where the track is wet/damp but it’s not raining, yes. That’s what they are specifically designed for, whereas all the four dry compounds are designed purely for when the track is dry.
@Hotbottoms No the height of the car is controlled by the planks on the floor. Too much wear on those and you are deemed to have been running too low. Other surfaces are measured against the “reference plane” which is essentially the level of the floor.
