That is very interesting information!

It is funny that, it works very good, the way it is done now (I think a lot better than with the ray). In normal situations (wheel contacts the ground) the results should be approximately perfect, because, the suspension is deflected almost correctly (although wheels are always a little too high, i guess).

Now you mentioned it, I noticed that the wheels don't deflect, when the car is just falling.

A simple hack to fix this, is to just deflect the wheels on default. They will automatically go up, when they touch ground. When there is no ground contact, deflect them again.

As I have the wheels as rigid bodys in my bullet simulation, it would also be no problem to make them dynamic objects. The problem is on the one hand the axis kinematic (although a simple connstraint with a fixed rotation center is pretty easy and on the other the connection with vdrift. Do you really think it is that difficult to calculate the deflection by adding some damping +spring forces (I'd just assume McPhersons) and a weight?
I didn't mess with those parts in vdrift yet.

Edit: A quick fix for some problems is to just enlarge the collision cylinders for the wheels by ca. 20cm. Although this is alsoby no means satisfying solution.
