Not sure, my wild guess; they're to inspect the crash bar innards/fasteners. They have weird ridges/fastener threads though which is odd. Mine had the same thing, before I tossed that whore in the garbage for a steel bumper.

Well if it's going to go faster, it should stop faster too. New Cross-drilled brake lines promise shorter stopping distances -- for a reasonable price too!
