Bumper height

Is that rule hard set or can we put it just 1" or .5" off the ground? Obviously ground clearance is ideal, but we want to make sure the bumpers dont break off.

After re-reading the OP's two posts, I'm confused as to what the question is...

The bumper rule is unchanged from last year regarding the heights. The short form is that the bumpers must be 5" tall and have a minimum ground clearance to the bumpers of 2" and a maximum of 5". Since the OP apparently has some part of their frame (a pic or drawing would help) 2.75" off the ground, there is a mounting location for the bumpers within the permitted zone.

Of course, this may alter how the OP wants to attach the bumpers, but everything is about adaptation to opportunities, not dealing with problems
