You need a 90 degree side view to be able to see the car work better in my opinion.
It looks like to me that the front is rising at the same time as the car is pitch rotating, which makes the rear look like it is squatting as it is not rising as fast as the front is. Most ladder bar cars rise in the back under acceleration
Have another look at it up closer from the side
BTW, what is the 60 ft. times on that run?
