UFC champion Anderson Silva to start the Kobalt Tools 500 at Phoenix International Raceway on Sun., Nov. 13, in the official pace car, a Toyota Venza. As the official pace car driver in Phoenix’s NASCAR Chase for the Sprint Cup event, the 36-year-old mixed martial artist will take an honorary lap on the newly repaved and reconfigured one-mile oval. "The Spider" tells PaddockTalk.com that he has "been a NASCAR fan for a long time." Silva is pictured above with his Bumble Bee-themed Camaro from West Coast Customs.
