Coil bind
At rest the air dam (red) of a car appears several inches above the ground.
At full speed the air dam appears much closer to the ground.
Coil bind is a style of setup used in various levels of
tires. Coil bind uses aerodynamics
to produce grip.
As a car approaches the end of a straightaway, the
ground effects. Under braking, weight transfer causes more weight to shift forward as the vehicle decelerates. This helps to maintain the low-pressure area below the car by keeping the front of the car low to the ground. While coil bind setups do yield faster lap times, the cars are more sensitive to turbulence
generated by nearby cars.
