Factory48 Motorsports is happy to announce that we are partnering with Radical Ventures again this year to run the 25 Hours of Thunderhill race. The race will be held at Thunderhill Raceway Park on Dec. 3-4th 2011.  The 25 Hours of Thunderhill has become a staple of endurance racing drawing top competitors and teams from all around the world. The unpredictable nature of the weather and the challenging track layout make the event especially exciting for both drivers and fans alike.

Last year the Factory48 sponsored Radical completed all 25 hours and finished 1st in class (ESR). This year we’re shooting for the overall as well.
