F1 RESULT(1) Not Used Not Used Not Used
F2 RESULT(2) Roll Angle deg The suspension roll angle and is defined as the arctan of the difference in wheel center displacements divided by the difference in wheel center y coordinates or:

atan((rdisp-ldisp)/abs(rwcy-lwcy)

The sign is positive when the right wheel is in jounce and the left wheel is in rebound as in a left turn.
F3 RESULT(3) Tread Width mm The distance between the left and right tire patch points.
F4 RESULT(4) Tread Change mm/m The change in tread width due to a change in wheel displacement and is defined:
Orientation A:
(C(8,3)+C(8,9)-C(2,3)-C(2,9)+slr*(C(10,3)+C(10,9)-C(4,3)-C(4,9)))*2000/(C(3,3)+C(3,9)+C(9,3)+C(9,9))
Orientation B:
(-C(8,3)-C(8,9)+C(2,3)+C(2,9)+slr*(-C(10,3)-C(10,9)+C(4,3)+C(4,9)))*2000/(C(3,3)+C(3,9)+C(9,3)+C(9,9))
