Hi @Anto,
Great work, really!
Finally, I build the buggy yesterday and it's looks amazing and it's fast as hell! :) But...there is one, a really big problem. Please, check the attached file.
When the buggy has few collisions, for example with wall, or I'm speeding up and immediately go back, then real axle is disconnected from rest of the car.
Did you have the same issue?
