Yes I thought so 
… I see these left and right track torque on screen and I thought… you can probably hook them up directly to an axis input.
I fixed the problem with the roadwheels shifting on the left when I run the simulation with the Tiger1.
I had 2 suspension handles mixed up in the blueprint 
Adding the tracks now… looks super cool!
O and one thing… How can I make sure the sprocket also collides with what it runs into… currently the sprocket does not seem to have any collision. (and the idler also)
