For 2006, the lineups were the same. Mazda's Tri-Point Motorsports Mazda 6 in Speed Touring Cars, and #36 with Michael Levitas and TPC Racing.
2006 started with a tremendous 'Bang', the good kind, as Randy and the TPC Racing #36 won at the world-renowned Rolex 24 Hour at Daytona! Co-driving were Michael Levitas, Spencer Pumpelly, and last years Alex Job #24 Porsche teammate, Ian Baas. It was a great team effort in prep, pit, and pace.
Randy returned to the TPC Porsche two more times with a strong finish at VIR. Randy also drove for Bob Miller in the At Speed Motorsports Porsche #23 in the Grand Am Rolex series with a victory at Road Atlanta, the closest finish in Grand Am history to date.
Randy continued with the Tri-Point Motorsports Mazda 6 in Speed Touring with wins at St Pete, Denver and Road Atlanta and top five's at most of the other tracks. Randy finished a close second in the championship with Mazda winning the Manufacturers' Championship.
2007 would prove to be a very good year for Randy who returned to Mazda and Tri-Point Engineering in the #73 Mazda 6 with two wins and several top 5s. Randy also joined K-PAX/3R Racing for the SCCA World Challenge GT series in a Porsche GT3. At Watkins Glen, Randy made history by sweeping all three SCCA World Challenge races, a result not matched in any form of auto racing. He took the pole and won both Touring Car races in his Tri-Point Mazda 6 and also won the GT race on his new K-PAX/3R Racing Porsche GT3. Randy went on to win another race at Toronto and took several podiums, giving him the World Challenge GT Driver's Championship! In the Touring Series, Randy finished second to his Tri-Point teammate Jeff Altenburg for the TC Driver's Championship.
In 2008, Randy rejoined K-PAX/3R Racing for another run at the GT Championship. He also said goodbye to Tri-Point Motorsports and joined APR Motorsports in a Volkswagen GTI in the Grand-Am KONI Challenge Series Street Tuner class. Randy also ran in The Rolex 24 at Daytona with the Stevenson Motorsports #57 Pontiac GXP.R team, finishing a satisfying ninth in class. Randy went on to win GT races at Sebring, Watkins Glen (four in a row!), and Detriot and had podiums at several other tracks, giving him his second consecutive World Challenge GT Driver's Championship. Randy's new APR team was not quite as successful but had some fun races and gained experience.
Randy started 2009 at the Rolex 24 hours of Daytona in the Gotham Competition #26 Porsche 911 GT3, finishing a strong tenth. Randy left APR Motorsports to join Compass360 Racing in a Honda Civic Si, with co-driver Christian Miller, in the Grand-Am KONI Sports Car Challenge ST class. The team was quickly successful with wins at Homestead, New Jersey Motorsport Park, and Miller Motorsports Park, as well as podium finishes at several other tracks. The team went on to win the Street Tuner Driver's Championship with Christian Miller (Randy missed a few races due to WC conflicts), as well as the Team Championship and the Manufacturer's Championship for Honda.
Randy also rejoined K-PAX/3R Racing for the WC GT season, but this time in a Volvo S60. The team approached the season as a development year for the new Volvo and had mechanical issues in the first few races. The team continued to improve and won at Autobahn Country Club with Randy and Road Atlanta with teammate Andy Pilgrim. Randy also had a podium finish at Mazda Raceway Laguna Seca which helped to give Volvo third place in the Manufacturers' Championship.
In 2010, the Volvo found its pace, and Randy won four races on his way to a fourth WCGT championship. The K-PAX team continued their long history of first-class preparation and performance.
