Correct pinion angle depends on the type of rear end. For a leaf spring rear end, normally this is 6-8 degrees, but for a modern multilink rear end this should be about 1-3 degrees. This reason for this is the relative 'tightness' of the rear ends. As a car accelerates, the diff will want to rotate up - a multilink rear end is mounted to the car at 4-6 points, so it is very tightly held to the car and the amount of upward rotation is minimal. During full acceleration, the diff rotates upwards about 1-3 degrees bringing the diff into alignment with the rest of the drivetrain. Leaf springs are much sloppier and less accurately postion the diff, and the springs also develop a degree of bind, so the diff rotates upwards much more, hence the bigger angle. The leaf spring bind is the reason for 'axle tramp', and tramp rods are fitted to minimise this bind in the springs.
