Best to hit their website and see if they publish their rulebook. NHRA has some but most is in their rulebooks that come out each season. Starts January to most new rule books come out in december.
In your pic, from what I've seen to go under 11.50 you only need the grey part. The ones that cross the door on an angle can be removable so it's easier to get in and out.
