attachment point and the rotation of the spin axis
for the wheel. This is defined in wheel space, wh ich
means that if you alter the position or rotation of
the wheel the space moves as wel l and maintains
its offset rotation and translation with respect to
the wheel. When you assign a wheel b ody to the
Car-Wheel constraint, Wheel Space’s t ranslation is

axis is aligned to its X a xis.
Suspension Rotation—This level allows
independent rotation of the suspension axis with
respect to the Chassis Space. This means that your
suspension axis doesn’t have to be perpendicular
to your spin axis, allowing for a greater range of
constraint setups.
