To help kick off NASCAR weekend, Strikeforce fighter Josh Barnett joined Kyle Busch and NOS Energy Drink at the Celebrity Go-Kart Challenge at K1 Speed in Ontario, CA .

This special charity event benefited the Kyle Busch Foundation ( NASCAR driver Kyle Busch and Formula DRIFT driver Chris Forsberg hosted the event racing against celebrities that included Actor William Fichtner, Kimberley Leemans from How To Make it In America, and Chef Holli Winner of “Hell’s Kitchen.”

30 drivers were given driving instructions by Kyle Busch and Chris Forsberg to better prepare them before getting on the track. Spectators were not only treated to some exciting racing but also had the chance to play video games in the NOS Energy Gaming area.

Kyle Busch came out on top with the fastest lap time of the day, but the real winner was the Kyle Busch Foundation who received a check for $10,000 from NOS Energy Drink.
