The front axles in the 1987, 88 and 89 V1, V2, V3 models are wider than the rear axles.
Due to a stack up of tolerances, the rear axle may also be offset to one side or the other when compared to the front axle. This can be as much as 44 mm
(1-3/4") on the V1 and V2 models, and as much as 57 mm (2-1/4") on the V3 models.
Because the front and rear axles are parallel to each other, this condition will not affect tire wear or vehicle handling.
