Twenty-four teams to vie for Pit Crew Challenge (cont'd)

• Round One: Teams seeded Nos. 9-24 -- again, according to series car-owner standings -- compete here. They also retain their seeding for the rest of competition. The fastest front-tire carrier, front-tire changer, rear-tire changer, rear-tire carrier, jack man, gas man and catch-can man in both seeding- and first-round competition will win individual titles.

• Round Two: The eight teams who prevailed in Round One competition advance here, where they'll face the top eight-seeded teams. Eight teams advance to the next round.

• Round Three: This is the Nextel "call-out" round, the second new facet of competition. The highest-remaining seeded team begins by selecting -- or "calling out" -- its choice of opponent. The next highest-seeded remaining team then "calls out" its opponent, and so on. All eight teams compete once in this round.

• Round Four: The final four teams advance here, with two winners advancing.

• Championship Round: The winning team is crowned the 2007 champion.
