Calculation of the track drift:

–	If the convergence values are of the same sign (+/+ or -/-), subtract the smaller value from the larger, and then divide by 2.

convergence rear left wheel		convergence rear right wheel
+ 15′		+ 5′
	15′ - 5′ = 10′ 10′ : 2 = 5′

Track drift = 5′

–	If the values are of different signs (+/-), they must be added and then divided by 2.

convergence rear left wheel		convergence rear right wheel
+ 15′		- 5′
	15′ + 5′ = 20′ 20′ : 2 = 10′

Track drift = 10′

The result obtained is the real drift of the axle track from the vehicle longitudinal geometry.
