Last season was the final year of the Grand-Am Road Racing’s contract with KONI. In 2010, Grand-Am partnered with Continental Tire. The series was renamed the Continental Tire Sports Car Challenge. Obviously, this new arrangement also meant that after ten-years, teams would no longer be competing on Hoosier spec DOT-approved tires.

The cars in the series are relatively unchanged from their road-going counterparts – modifications are mandated mainly for safety – roll cages, window nets, etc. They also used spec DOT-approved tires produced by Continental. Based on performance potential, the cars were divided into one of two groups:

  • Grand Sport (GS): The quicker of the two classes - the group features the larger displacement engines as well as smaller four-cylinder motors with forced induction systems. The power-plants produce between 350 and 405-horsepower. Minimum weights range between 2,900 – 3,300-pounds, which is dependent on the motor configuration and displacement. This class includes cars such as the BMW M3, Ford Mustang, Porsche 997 and Porsche Carrera.

  • Street Tuner (ST): The smaller displacement cars compete in this class in which engines typically produce between 170 and 240-horsepower. Popular vehicles found in this group are the Volkswagen GTI, Acura TSX, Mazda RX-8, Mazda MX-5, Honda Civic Si, BMW 328i, Chevrolet Cobalt SS and Mini Cooper S.

The 2010 season consisted of ten race weekends and started in January at Daytona International Speedway, which was followed by a second event in Florida at Homestead-Miami Speedway. In April, the series would visit Barber Motorsports Park in Alabama and then move on to Virginia International Raceway. Round five would be conducted at Lime Rock Park. This would be the first of two race weekends where the Grand Sport and Street Tuner classes competed separately. The teams traveled Watkins Glen International in June and after this event, race weekends took place at the Mid-Ohio Sports Car Course and New Jersey Motorsports Park. In August, teams made the trip to Canada, where the action would take place on the streets of Trois-Rivieres, Quebec. This would be the penultimate round and was the second weekend that the two classes had their own race. The finale was held at Utah’s Miller Motorsports Park.

The 2010 Grand-Am Continental Tire Sports Car Challenge season kicked off at Daytona International Speedway. The event titled, the ‘Fresh from Florida 200’, was a support race for the 48th Rolex at Daytona weekend. Teams would compete on the twelve-turn 3.56-mile roval for three-hours.

Forty Grand Sport competitors receive the green flag for round one of the 2010 Grand-Am Continental Tire Sports Car Challenge at Daytona International Speedway. On the pole is Andy Pilgrim in the Fall-Line Motorsports BMW M3. On the outside of Pilgrim is the Multimatic Motorsports Ford Mustang Boss 302 R driven by Joe Foster. In row two are the Ford Mustang GTs of Rehagen Racing and Roush Performance.
Sharing the No. 13 Rum Bum Racing BMW M3 were Matt Plumb and Gian Bacardi. Barcardi, who was in his first professional race, qualified the BMW in the nineteenth spot. When he stopped for the driver change, he was in second place. Plumb moved back up the race order and pitted during a late caution for two tires. With fresh rubber, he was able to chase down and pass Terry Borcheller and Charles Espenlaub for the win.
Lawson Aschenbach earned his second consecutive Street Tuner victory at Daytona. He shared the win with David Thilenius, who previously competed with Bill Fenton Motorsports. Thilenius qualified the No. 74 Compass360 Racing Honda Civic Si second fastest in Street Tuner. He was in contention when he handed the car over to Aschenbach. Aschenbach led the final seventeen laps for the victory.
Since 2003 BimmerWorld had competed in the SCCA Pro Racing World Challenge series, but in 2010, they joined the Grand-Am Continental Tire Sports Car Challenge championship. The two-car effort included a BMW 328i for Seth Thomas and Bill Heumann. And, the second entry was shared by team principal, James Clay and David White. In their Continental debut, Thomas and Heumann finished second in Street Tuner.
In the off-season, series regulars, Charles Espenlaub and Charlie Putman left Automatic Racing and joined Fall-Line Motorsports. Putman qualified the No. 48 BMW M3 in the sixth position. After the final round of pit-stops, Espanlaub made his way to the front and was in the lead by the fifty-fourth circuit. With three laps to go, he was unable to hold off Matt Plumb and finished second by a margin of 0.107-seconds.

The Riley Racing Mazda RX-8 was gridded forty-sixth overall and fifth in the Street Tuner category for the start of the Fresh from Florida 200. Co-driving the Mazda was Jameson and AJ Riley. Jameson led laps-12 to 23 and was in first place on the forty-sixth-circuit when he lost the top spot to the eventual winner, Lawson Aschenbach. The duo would fall out of contention and finish twenty-first in class.
The Street Tuner competitors receive the green flag for the Fresh from Florida 200 at Daytona. Leading the field of thirty-six starters is the pole-winning Freedom Autosport Mazda MX-5 of Derek Whitis and Tom Long. Beside the Mazda is the second-fastest qualifier, David Thilenius, in the No. 74 Compass360 Racing Honda Civic Si. In the second row are entries from BimmerWorld and Irish Mike’s Racing.
Freedom Autosport entered four Mazdas in round one of the Grand-Am Continental Tire Sports Car Challenge event at Daytona International Speedway. Leading the way was the No. 25 MX-5 shared by Derek Whitis and Tom Long. During the Street Tuner qualifying session, Whitis was the fastest driver and would start forty-second. Early in the contest, Whitis led four-laps, but the duo would finish seventeenth in class.
Another driver competing in his first Grand-Am Continental Tire Sports Car Challenge event and finishing on the podium was Steve Miller. Miller shared the No. 41 The Racer’s Group prepared Porsche 997 with the series veteran, Spencer Pumpelly. Miller qualified the Coco Logistics sponsored Porsche in the thirteenth position. Pumpelly drove the final stint and maneuvered his way to the front and finished in third place.
Co-driving the No. 46 Fall-Line Motorsports BMW M3 were Andy Pilgrim and the team owner, Mark Boden. Pilgrim put the BMW on the pole and led the first twenty-nine-laps of the Fresh from Florida 200 before pitting. He stopped in the wrong stall and was penalized. The pair fell down the race order and Boden was unable to make up the deficit. At the end of the contest, they were classified in the eleventh position.
The No. 26 Freedom Autosport Mazda MX-5 was piloted by Andrew Carbonell and Rhett O’Doski. The MX-5 was gridded sixtieth overall for the start of the event and nineteenth in the Street Tuner category. The pair moved to the front of the class and were in third place at the checkered flag. However, they lost five-points when it was discovered that the car was underweight during the post-race technical inspection.
The Street Tuner podium for Grand-Am Continental Tire Sports Car Challenge series. In the center are the winners, Lawson Aschenbach and David Thilenius. Standing on the right are the runner-ups, Seth Thomas and Bill Heumann. Their BMW was severely damaged during the test days earlier in the month but rebuilt in time for the Fresh from Florida 200. Completing the rostrum are Andrew Carbonell and Rhett O’Doski.
