Callaway Competition will field an extremely strong entry in the ADAC GT Masters with the most successful Callaway drivers in recent years and four Corvette Z06.R GT3s. In conjunction with Toni Seiler Racing, Ernst Wöhr and Giovanni Ciccone´s team will put four Corvette Z06.R GT3s, developed and built by Callaway Competition in Leingarten, on the ADAC GT Masters starting grid. Two of the four cockpits of the Corvettes which have undergone further tweaking for the 2013 season are already occupied by reigning ADAC GT Masters Championship runners-up Diego Alessi and Daniel Keilwitz, now in their third season hunting down titles together. Christian Hohenadel returns to Callaway Competition, sharing a Corvette with Andreas Wirth.

Ernst Wöhr: "We missed lifting the title in both driver and team standings last year by a very small margin but now intend to go back on the offensive with two sets of extremely solid drivers. Diego Alessi and Daniel Keilwitz have proven during the past two years that they can consistently be up there with the front-runners, and everyone in the team is looking forward to Christian Hohenadel´s return. We enjoyed a great deal of success with him in 2009 and 2010. Also, in 2010, Christian Hohenadel and Daniel Keilwitz won the FIA GT3 European Championship with us. Christian Hohenadel and Andreas Wirth, now in his second season with us, make a formidable pair. I hope we can bring the title home to Leingarten this year."

Giovanni Ciccone: "Our drivers have secured a total of 12 victories in the ADAC GT Masters and have a minimum of three years experience in the series. So, they are not only among the fastest and most successful in the ADAC GT Masters but also have a huge wealth of experience to draw on."

There will be a change of personnel on the Callaway Competition pit wall perch at this season´s ADAC GT Masters races. Giovanni Ciccone will take over the role of trackside team leader from Ernst Wöhr. Wöhr: "We decided that my partner Giovanni Ciccone should direct operations in this year´s ADAC GT Masters. I am retiring from the pit wall station and will not be at all of the races in the ADAC GT Masters. I will, however, continue to be in charge of seeing updates through to completion."

The drivers of the two Corvette Z06.R GT3s to be deployed in conjunction with Toni Seiler Racing will be confirmed at a later date.
