Are the rules different for the Regular Figure 8 than the Street Stock 8?

I found this rule in the Regular Figure 8 rule book...

e.      AT ANY TIME YOUR CAR GOES FOUR TIRES OFF THE RACING SURFACE DURING THE FEATURE FOR ANY REASON YOU WILL BE DISQUALIFIED, NO MATER IF YOU ARE PUSHED OFF OR DROVE OFF UNDER YOUR OWN POWER.

I didnt even put that in bold lettering, it was clear as day in the rulebook and meant to stand out. And yes, it was missing in the street stock rule book.
