Calculate wheel track offset "S":
•
Wheel track offset "S" is the distance to left or
right between the longitudinal axes of the front
and rear wheels.
Track offset (S): ...........+ 3 mm (0.12 in) (= to right)
Permissible wheel track offset (S):
.........± 9 mm (0.35 in): datum is + 4.5 mm (0.18 in)
L
Note:
Key to measurement result:
Negative sign = wheel track offset to left
Positive sign = wheel track offset to right
