OK so next up is the suspension in my case I've made three different types of suspension; front, back and main suspension to start i'm gonna go through the main suspension seeing as the process is very similar to making the wheel rotation.

repeating the same process as earlier with the arrows except changing the curve so that it bend deformer goes down instead of a circle like so....

and again using an orient constraint except this time adding all axis to the constraint so that it affects all the axis (remember its the object to the controller not the other way round)

next up i need to limit the information of any transformations or rotations made (this also goes for the wheels previously)

to do so go into the attribute editor and scroll down to limit information this allows to in effect make it idiot proof (as my lecturer adequately puts it)

the idea here is to add restrictions on the controller as to how much you can move the controller so ideally you would want to move the controller (in effect moving its influence too) to the minimum amount of how much you want to move it check the box and then set its maximum to its opposite, in my case ive set the suspension to move as little as possible on all axis and then checked the box so that the value of the transformation will not go further then the value that's been locked in.

now that ive done that my body of my car will only rotate around all axis a slight amount in effect giving it body suspension that you would use if you were say animating the car going over a bumpy road.
