TEMECULA, Calif. – Former IMSA WeatherTech SportsCar Championship Prototype co-champion Eric Curran has signed with Callaway Competition USA for the full Pirelli World Challenge SprintX Championship, starting this weekend at Circuit of the Americas.

“We have a great history with Eric, and we’re very excited to have him on board,” said Callaway Competition USA owner Reeves Callaway. “He has significant experience in Europe with our Corvette C7 GT3-R. He held the fastest lap at the Red Bull Ring in Austria in 2016. Combined with his knowledge of the tracks across North America, he’s the perfect addition to our team for the SprintX championship.”

Having previously raced with Callaway Competition in Europe in the ADAC GT Masters, Curran will require no time getting familiar with the Corvette, which just celebrated a second place finish during its North American debut.

Most recently, Curran celebrated a third place finish in last weekend’s Mobil 1 Twelve Hours of Sebring.

“This is a really exciting time for me,” said Curran. “I’ve known Reeves Callaway, Mike Zoner, and everyone else on the team for 20 years, and its been a great relationship with them. We’ve been talking about me being a part of the Callaway Competition USA program, and here it is.”

Curran hopes to use the team’s existing momentum to fight for additional podium finishes.

“With a fourth and second place finish on a demanding course, it’s no doubt the performance is there for Daniel and the team,” added Curran. “(Co-driver) Daniel (Keilwitz) did a phenomenal job. With his background with Callaway Competition Germany and the Corvette C7 GT3-R, all the ingredients are coming together for a serious championship effort.”

Keilwitz and Curran will share the driving duties during the doubleheader event at Circuit of the Americas, splitting the 60 minute drive time in each race. All competitors will have a 10 minute window during the race to make the mandatory pit stop after the 35 minute mark, with required tire changes as well: a new regulation to the 2018 rules.

Each car will have to meet a pit lane delta; a specific minimum amount time of which the car must be in pit lane. The minimum driver change time will be set at 75 seconds, and the team has to spend an additional 45 seconds in pit lane from the moment they enter to the moment they leave.

The fastest lap in race one will set the starting position for race two, with the driver who started the first event swapping positions to finish the second.
