Round 4 of the GRAND-AM Rolex Sports Car Series took place in the beautiful track-resort at Virginia International Raceway. The SpeedSource team rolled into the facility determined to continue their recent success despite the recent competition adjustments thrown at them by GRAND-AM. Regardless, the driver duo of Emil Assentato and Jeff Segal captured the fourth straight SpeedSource podium of the season finishing 2nd in the #69 FXDD Mazda RX-8.

It was unclear to all what the effects of a 75-lb weight increase would have on the Mazda. The SpeedSource crew closely monitored all of these effects during the short practice session before the race.

Emil Assentato started his #69 FXDD Mazda RX-8 from 14th on the grid. Great strategy and work from the crew allowed the #69 to gain a wave-by under caution; catapulting it to the front of the GT class in the race's final hour. The #69 finished 2nd, capturing their third straight podium of the season. The #69 car now leads the GT standings.

The #70 Castrol Syntec Mazda RX-8 started from 2nd on the grid. Even with the added ballast from the Series Bomarito was able to pull off a great lap. Bomarito quickly settled into a groove at the start of the race and maintained the 2nd spot in GT. Co-driver and team owner Sylvain Tremblay kept the car at the front of GT. All things looked good until a broken rear sway bar affected the handling of the car. Jonathan would hold on for the 9th place finish. Mazda ladder drivers Adam Christodoulou and John Edwards, the #68 Mazdaspeed Motorsports Development Mazda RX-8, finished in 11th.

Jordan Taylor, #30 IDEMITSU/3Dimensional.com Mazda RX-8, won the pole and led the opening 21 circuits, with Lamb talking over and leading 29 laps. But Taylor was caught back in the pack and were unable to get back into contention and finished sixth respectively. The #41 Team Seattle/Global Diving/Dempsey Racing Mazda RX-8 GT, with drivers James Gu? and Leh Keen, finished a solid fifth where their teammates Patrick Dempsey and Joe Foster overcame more than one issue to finish 12th in the No. 40 Dempsey Racing Mazda RX-8 GT.
