This is awesome. I'd love measurements on your suspension height from the wheel cap to the top of the wheel fender. I started a thread on this with my data, and would be great to share.
Suspension Height - P3D vs. P3D+ vs. RWD
Also - my car has similar built weirdness, e.g., screws with no bolts on them in the same places as where you photographed them.
At least they're consistent...
I plan to measure this, but my driveway isn't the most level reference point. Once I can get the car in the garage (broken door) I'll measure the height.
