The 60' difference on my car is right at 1/10. In my case the car was accelerating very hard, was not as high in the air, and did not touch down till about 130' so I'm pretty sure it was the rear tire that tripped the 60' beam.

That skid plate looks like a good idea for protecting the oil pan but what kind of ground clearance do you have now? Looks like trailer loading/unloading could be complicated.
