Mills Racing has claimed victory and the inaugural Pirelli World Challenge SprintX Championship following a wild season finale Sunday at Mazda Raceway Laguna Seca.  A two-way fight for the win of the 60-minute race came down to the final lap, when contact between the then-leading No. 46 Mills BMW Z4 GT3 of Michael Mills and the Chris Beaufait-driven Racer’s Edge Motorsports SIN R1 GT4 gave way for Tim Pappas to take the lead and cross the line first.  However, Pappas’ Black Swan Racing Porsche 911 GT3 R received a post-race time penalty due to not meeting the 90-second minimum pit stop time, handing the race win back to Mills and co-driver John Edwards.
