I do like the idea of getting the inside nuts protruding on the inside out of the equation.

I would agree the loop mentioned is better then nothing, just not by much.

I am puzzled by those who are so adverse to drill a couple of holes, but have little worry about how much damage a DS can do with a combined 12"? overhanging/swinging yoke and u-joint at say 100 mph just under your seat. The rotating twisted mess will rip those arms off in less then a second (6000 rpms, thats 100rpms/hits).

The design is IMO "very lacking" (edited) and may only serve the purpose of passing tech. Even the other guys hanging crossmember safety loop is as per designer NOT for competition use, and I give him
for admitting that.
