I think the longest regulated distance is from the floor to the top of the engine cover. The shots have to be exactly level, though, to avoid the angle to the camera becoming an issue. Maybe the top of the rear wing to the floor at the rear could be even better, with less parallax and with parallel straight lines available.
Also, can't the wheelbase not be changed to a point just by suspension adjustments? And even change a tiny bit with speed? I'd think that the distance from the front of the front wing end plate to the rear of the rear wing end plate could be a better measurement of car length, or at least more constant.
Just throwing in some ideas. Looking forward to more comparisons!
Seems a good idea. I would assume the floor to be parallel to the reference plan and would try to get a perpendicular line to the floor, passing on the intersection of the rear wing end plate rear surface with a line parallel to the floor, at the height of the wing fixture, in order to avoid possible flex due to aero forces. Would do the same for the front wing.
With that, one could have the max point for a calibration line (FW2RW).
For the min point for the same calibration line maybe the distance between the top of the tube and the floor (TB2FL)?
And for a 3rd and average point, just to check if it's linear or not, due to distortions induced by the lens (and just because...) the distance between the floor and the top of the engine cover (FL2EC), and achieve something like that
With excel would be simple to have any 4th point in between those or, do the math
) ... the old conclusion still stands
