lazybitgames: I solved it like in the picture below. But is it crazy 
If you could add calling overlap event for wheels (or axles with wheel identification) in next version, it would be done just in about two nodes instead of this, but don’t know if it is possible for you.
I don’t think that comparing names of traced actors (strings) and casting every new traced object for detecting if it is that my object is good for performance. Better would be create new collision channel just for this situation and that should fire begin overlap event. In that case will be not needed to compare strings and doing casts.
Atleast I limited this solution for car that is driven by me, so I will see. Anyway, great plugin.
