A safety car intervention just before the halfway mark of the inaugural edition of the Mazda Raceway California 8 Hours meant that the advantage of the leading #29 Audi Sport Team Land R8 was reduced to naught. The #44 Audi Sport Team Magnus R8 is still in second, with the #11 Belgian Audi Club Team WRT R8 making it a Audi 1-2-3.
Behind the leading Audis the #43 RealTime Racing Acura occupied fourth position, but an ill-timed pitstop dropped the car off the lead lap. The #58 Porsche Motorsport North America by Wright Motorsport 911 and the #9 K-PAX Racing McLaren managed to get back on the lead lap because of the second safety car intervention and are now in fourth and fifth respectively, less than ten seconds behind the leader.The battle for the GT3 Pro-Am honours is evolving in favour of the #54 Black Swan Racing Porsche, which is in eighth overall. It has a full lap on the second car in class, the #77 Calvert Dynamics / GMG Racing Porsche. In GT4 the #3 TRG Aston Martin is still in the lead, with a two lap advantage on the #8 HKG Racing / GMG Racing Porsche.
