While Rapone led the entire way, his gap was shrinking at the finish as Joel Lipperini was charging from the rear of the field toward the leader. Rapone crossed the stripe 3.048-seconds ahead of Lipperini for a perfect debut weekend with the Series.
Rapone was recruited for the weekend by his brother and Pirelli World Challenge Touring Car Competitor Anthony Rapone.
"It's our first time out in World Challenge and it was good to make a good showing for myself," Rapone said. "I had to do that, especially after my brother's crash [Saturday] in Touring Car.
"I knew from the beginning that [Lipperini] was going to be a good threat. I tried my best to get as much distance between us as possible. I started to fall off a bit toward the end and I saw him coming, closing in. I just gave it it's all and just prayed that I could hold on. I didn't realize I turned the fastest lap of the race, but I'm not surprised because I was balls to the wall!"
Lipperini, a multiple-time SCCA Club Racing National Champion in Showroom Stock classes, showed up at the track early on Sunday morning and missed the qualifying session on a spur of the moment decision.
He started from the rear of the field and marched to the podium finish, earning the Optima Batteries Best Standing Start for improving three spots on the opening lap and the Sunoco Hard Charger award for improving six overall positions throughout the race in the No. 18 RACELABZ Honda Fit.
"We got the car finished at midnight on Wednesday night," Lipperini said. "We drove up to Lime Rock and ran the SCCA National. We heard World Challenge was up here and decided to drive up all through the night, get here and start scratch.
"At one point it was eight seconds and then I was chipping off a half to three-quarters of a second per lap but I got some tough breaks in traffic. It was a lot of fun. B-Spec is the wave of the future!"
Jonathan Start, a two-time winner during the class's debut at Miller Motorsports Park, finished third for the third in the No. 00 Kawartha FIAT/Speedlogix Fiat 500 time during the weekend.
Cooper's finish, coupled with Lamb's mechanical failure, stretched the Championship lead to 135 points, 1161 to 1026. Winchester (767 points) and Holbrook (748) are in a distant battle for third, followed by Tristan
