This is also the point at which we need to set our driveline angle relative to the pinion. Ideally, we want a 0-degree pinion angle that creates a straight line from the crankshaft through the transmission, driveshaft, and the pinion while the car is under load. But to get that we have to compensate for the upward movement of the differential under load with a slightly negative pinion angle. For our purposes we went with a negative 2-degree angle, which should zero-out when under hard throttle.
