HAIRPIN
A relatively slow corner with more than 120 degrees of direction change.

HEEL AND TOE
The process of keeping consistent pressure on the brake pedal while blipping the throttle for downshifts. This technique is actually a misnomer (it has historical equity, however) since modern pedal layouts enable the use of the ball of the foot on the brake while at the same time using the right side of the same foot to rev (blip) the throttle. This is an essential skill that all great drivers use to shorten braking zones and turn fast laps.

HOOK
A spin generally to the inside of a turn. This is the most common spin in racing. Differs from a “second reaction hook-slide.”

HOOK SLIDE
The second-reaction slide.
