Editor's note: Scroll down for updates...

NASCAR's three-week trek to the West Coast comes to a close Sunday in Fontana, California, so see how drivers and teams are preparing for the Auto Club 400 at Auto Club Speedway. 

Kurt Busch has been blistering fast all weekend long, sweeping the top spots in qualifying and each practice session. Busch's team is already busy in the Sprint Cup garage preparing his No. 41 Chevrolet. 

Busch's team is not the only one hard at work in the Auto Club Speedway garage, though. 

While the crew members are hard at work, the drivers are making the rounds spending time with fans, hospitality guests and sponsors. 

Kevin Harvick is on an incredible streak of 1-2 finishes in the Sprint Cup Series, however, the defending series champion is excited about Sunday's Auto Club 400 for another, more unique, reason. 

Most are looking to the Stewart-Haas Racing teammates of Busch and Harvick as the favorites for Sunday's race, but former champion and Team Penske driver Brad Keselowski is optimistic about his chances at spoiling the SHR party.
