Help! Root bone is still acting with collision when its deleted!

Im trying to make a car and I have everything properly setup but when I play the game and try to move the car tilts and wobbles around like its on a pillar. There is no collision setup to do this because I deleted the root bone collision in the physics asset but it still acts as if it has collision. Another thing that confuses me is that the root bone collision size when its created in the example vehicle is super tiny and barely noticable. But when I create it for my model its really big. Why is this? I have the units setup correctly from blender to UE4 and there was no FBX importing errors.
