With just two weeks and two races left until a new Sprint Cup champ is crowned, Brad Keselowski heads to Phoenix confident about his chances because...

(Keselowski) "I feel like our cars have been very, very strong and my team has been performing phenomenally."

Jimmie Johnson is not easing up just because he has a slight lead over Keselowski.

(Johnson) "Seven points is nothing to feel comfortable about and to relax on, so we're still going to go into Phoenix and act as if we're behind."

And Kyle Busch, who did not make the Chase this year, is making plans for next season.

(Busch) "As far as 2013 goes, I mean, we just continue to evolve and continue to try to get better, and strive at what we need to so we can make the Chase next year."

And Brian Vickers will be racing full time in the Nationwide Series next season for Joe Gibbs Racing, with Dollar General as his sponsor.  Vickers was driving a partial Sprint Cup schedule for Michael Waltrip Racing, and will continue to share that car with Mark Martin and Waltrip.
