Flying finish
End of the timed part of the stage. Rally cars go flat out up to this point and begin slowing down only from then on. The time control which marks the proper finish of the stage is some hundred meters further down the road, that is where car stops and time card is stamped.
Footprint
Tyres are grooved to improve grip and consequently all of tyre's surface is never in contact with the ground. Contact area is called footprint. Footprint area is determined by width of the tyre, tyre radius, tyre pressure and rubber compound hardness.
