RECOVERY
Recovery is the third phase of skid control (CPR). As a slide stops, the outside springs unload, transferring weight to the inside tires. Good drivers know that they must straighten the steering wheel to prevent a second-reaction hook-slide.

REDLINE/REV LIMIT
The maximum RPM depicted on the tachometer that an engine can turn without damage to its internal components.

REFERENCE POINT
Any point on or beside the racetrack which a driver uses to trigger some action; turning in, apexing, brake application point, etc.

REVS
Term used to describe the RPM (revolutions per minute) of the engine. Short for revolution.

ROAD CAMBER

The upward or downward movement, left or right along a car’s centerline, in response to cornering forces.

ROLLCENTER
A point in space determined by suspension geometry that the CG rolls around at each end of the car.

ROTATION
Deliberate over-steer caused by the release of the brakes during the trail-braking phase of brake turning.

Revolutions per minute.
