I fitted my adj pinion snubber and it makes contact with the floor pan even on the lowest setting.

I estimate theres about 3/16ths of crush from the "zero lash-just touching" position.

Not a huge amount but am I going to hurt the car by driving it with this setting, or will I just wear through snubbers more quickly?
