How do I get 4 wheel steer?

In the old spintires I could set the rear tires to a negative steering angle to get 4 wheel steer, in this game when I do that it says something about clamping node minimum value 0. Is there a new way to get 4 wheel steer or did the creators fix something that wasn't broke?

FYI I am xELITExMODAx on steam, you can find my realistic K5 Blazer I made in the workshop for Mud Runner. http://steamcommunity.com/sharedfiles/filedetails/?id=1192910790

I just realized the negative steering angle was fixed in the latest update. Thank you for listening! 🙂
