Go into the .truck file, find this part:
cinecam
-.0355, 1.75, 0.45, 5, 8, 23, 27, 3, 21, 14, 33, 80000, 1000
Play with the first 3 numbers, one of them will move the camera up and down, other two will move it forward/back and left/right. Might take a few minutes to figure out which is which. I don't think you can run in official events like this but I'm not sure. (Cinecam is a node which has some weight to it, so it changes the handling of the truck.)
