It says that bolts aren't used to calculate the frame perimeter. That's it. Remember, frame perimeter is well above most drives this year, and the drive area is where 90% of the minor protrusions will be (axles, frame bolts, stuff like that).

There has been concern that bolts in the lower frame (say, axles) will be outside the frame perimeter. With this update simply stating that bolt heads won't be counted in the frame perimeter determination, there are a number of possible interpretations:

1) Bolt heads are not counted in determination, so you can't have bolt heads on the frame perimeter sticking out because that's a violation of the frame perimeter restriction. (exception: bumper mounting hardware)

2) Bolt heads on the frame perimeter are fine (due to parts of <R07>), but other bolts are not.

3) Bolt heads sticking outside the frame perimeter are not an issue at all.

I'm guessing they meant #3, but there has been no clarification of this issue at all other than, bolt heads are not counted when determining the bumper perimeter. If they meant #1, then a lot of teams are going to be hurting the first day of events. If they meant #2, then a number of teams may want to look at their drive area and make sure they're OK.
