Just short of negligible. You're talking about a small amount of 1/16" to 1/8" flat plate, strategically applied, and a part of a series of aluminum rivets. Your unit of measurement would probably still be ounces for most chassis configurations.

I've had two fail that I can remember:

At Brunswick Eruption 2007, 1618's robot tipped and sheared the two 3/16" rivets holding together the tower on one side.

At Peachtree 2011, 2815's roller claw was run into the alliance station wall, causing the rivets holding the lower part of the roller claw to become loose enough to become an issue. We decided to scrap the lower roller in favor of a flat plate.
