Lateral G (red) and longitudinal G (blue) forces are plotted here for a lap of Buttonwillow Raceway's west loop, recorded by our Racepak G2X system. A positive value for lateral G indicates a right-hand turn, a negative value the opposite. The top trace (black) is speed, shown here for reference. Note how longitudinal G forces change sharply from positive to negative at the end of each straight as the rider goes from accelerating to braking.
