Ok, later is now.

In this section you see the numbers in the y column decrease. This is to simulate stalling as the floor gets closer to the track. The x column is the... *sigh* "reference" to a separate "definition". Sorry, it's kinda hard to explain.
<m_aero_max_front_height value="-0.005" />
<m_aero_min_front_height value="0.075" />
<m_aero_max_rear_height value="-0.005" />
<m_aero_min_rear_height value="0.075" />
Basically it references this, which defines the height range of the downforce simulation. So the "0.0000" in the x column references the "-0.005" in the latter definition part. Hope that makes sense somehow. Why the original x column doesn't just use the actual ride height as reference, instead of a reference to a separate reference, I don't know, but it might be easier to change the ride height in testing if the whole x column doesn't have to be redone every time. Would certainly make my life easier though.
In the suspension data, these can be found. <MinHeight value="0.00" /> <MaxHeight value="0.09" /> They seem to specify the absolute height the car (or suspension) can be. They line up with the aero height reference, so thankfully it seems it's a 1:1, instead of another reference. As for what it means, I don't know. Seems to be an arbitrary value.
Take everything with a bag full of salt, I'm just a modder. No one told me what they mean, I'm just giving my best guess based on my own testing.
