While Fall-Line Motorsports led both of Thursday’s Continental Tire SportsCar Challenge sessions at Sebring International Raceway, John Edwards cautioned not to put too much stock in the fastest laps posted by himself and teammate Shelby Blackstock.
Edwards led the afternoon session with a lap of 2:17.402 (97.990 mph) in the No. 46 Fall-Line BMW M3 co-driven by Trent Hindman. Slightly quicker in the morning session was Blackstock, who ran 2:17.144 (98.174 mph) in the No. 48 Fall-Line Motorsports BMW M3 co-driven by Ashley Freiberg.
“Obviously, our one-lap speed is very good,” Edwards said. “The real story is who’s going to be best at the end of the race and who runs best on worn tires.”
The afternoon session saw Shane Lewis post the second-quickest lap in the Grand Sport (GS) class in the No. 12 Bodymotion Racing Porsche 911 co-driven by Andrew Baxter at 2:17.759 (97.736 mph). Third was Andrew Aquilante in the No. 32 Phoenix American Motorsports Ford Mustang Boss 302R with a lap of 2:18.115 (97.484 mph).
“We were down near the bottom in the morning session, so we went out on brand new tires to start the afternoon and I was hauling,” Lewis said. “I wish we could keep up that pace. This team hasn’t raced in the Continental Tire Challenge, and we’re still coming to grips with the best setups for the tires.”
David Murry led the Street Tuner (ST) class for the second straight session, improving on his morning time with a lap of 2:26.442 (91.941 mph) in the No. 64 TGM BMW 328i. Daytona winner Eric Foss was second at 2:26.714 (91.770) in the No. 56 Murillo Racing/Mosing Motorcars BMW 328i, followed by Terry Borcheller in the No. 23  Burton Racing/Automotive Chemicals BMW Group/Excelda Manufacturing BMW 128i with a lap of 2:28.022 (90.959 mph).
Even though he was second-fastest in both sessions, Foss was more pleased by the progress of co-driver Jeff Mosing, who was running the full Sebring layout for the first time on Thursday. Mosing improved 1.2 seconds in the afternoon session from his best time in the  morning.
While Mosing had never been on the 17-turn, 3.74-mile layout, he participated in a driving school on a shorter layout here eight years ago.
“My very first driving school was here on the club course in 1996, and I was never around the longer course,” said Mosing, who joined Foss in winning the season-opening BMW Performance 200 at Daytona International Speedway in January. “All that work on the simulator definitely helped me learn the track. The simulator didn’t include the bumps, but Eric warned me about them and I got faster as the day went on. I knew I was going to have fun here, and I really did.”
The Continental Tire Challenge will conclude the test with a pair of sessions on Friday from 8-9:15 a.m. and 1-2:30 p.m.
