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): + 4.5 mm (+ 0.1772 in) (= to right)
Permissible wheel track offset (S):
.............................................. ± 9 mm (± 0.3543 in)
based on + 4.5 mm (+ 0.1772 in)
[Integral ABS]
Track offset (S): + 3.5 mm (+ 0.1378 in) (= to right)
