Lexington, Ohio – Lawson Aschenbach led the first GTS Practice session at the Pirelli World Challenge Grand Prix of Mid-Ohio presented by Honda Racing HPD.

Aschenbach, piloting the No. 10 Blackdog Speed Shop Chevrolet Camaro Z28, posted a best time of 1:27.966 at 92.408 mph on the 2.258-mile course.

Parker Chase posted the second-fastest time during the session. Chase took the No. 19 Performance Motorsports Group Ginetta GT4 to a session-best time of 1:28.260 at 92.101 mph.

Just 0.360-seconds behind that was the 1:28.620 Lap Time of Brett Sandberg, putting the No. 13 ANSA Motorsports KTM XBow GT4 in third. Sandberg’s top speed registered at 91.726 mph.

Fourth, fifth and sixth places all fell within a half-second of Sandberg’s time with Jeff Courtney, Scott Dollahite and Nate Stacy regsitering those positions. Courtney’s No. 99 RecStuff.com/Kenda/TBA Maerati GranTurismo MC Trofeo posted a 1:28.644 at 91.702 mph that was good enough for fourth. In the next spot, the No. 46 SDR Motorsports/Lotus Lotus Evora registered a 1:28.923 at 91.414 mph with Dollahite behind the wheel. Stacy’s 1:28.971 at 91.365 mph in the No. 14 Roush Performance Road Racing Ford Mustang Boss 302 ticked a hair slower than Dollahite’s Evora and was just thousandths of a second outside of the 1-second differential to the fastest lap time.

The majority of the remainder of the entrants in the 15-car field posted times within a two-second differential from the leader during the overcast, 80-degree weather.

GTS teams and drivers hit the track for Rd. 13 Qualifying session on Friday, July 29th, at 12:15pm EDT.

Lawson Aschenbach, GTS Practice Leader
“That was a good lap later in the session. We determined that we should make a “mach” qualifying run since it is a similar time for Friday’s qualifying. So we wanted to make sure we had a good plan going forward. I am very happy with the work the Black Dog guys have done with the car. We have been making a lot of changes over the last couple of races to try and find some more speed in the car. We’re trying to keep up with the GT4 cars. I think we found some stuff. This team never sits idle. It’s a testament to their work ethic. I couldn’t tell how many laps I have put in at Mid-Ohio. But I can tell in the first five laps of a session if the car is good or not. It’s one of the best tracks in America. It’s a driver’s track. This is a physical track and I hope our car is good enough that I’m not seesawing at the wheel. With a sprint race, you are giving 101 per cent to win the race and it can be very physical. That is our plan here at Mid-Ohio.”
