Dyson Racing was one of the founding teams of the Rolex Sports Car Series, winning sixteen races and two drivers' and two team championships from 2000 through 2002.

Dyson Racing ran their Riley and Scott in the inaugural year of the Grand American Road Racing Association. James Weaver won the championship, his second with Dyson Racing, winning four races, with two thirds and two fourths in nine races.

James Weaver won his second Grand-Am championship in a row in 2001, with Butch Leitzinger only twelve points back in second. Dyson Racing finished second or higher in ten of eleven races, winning half of those in 2001.

Chris Dyson, who had made his team debut at the 2001 Watkins Glen 250, finished second in the 2002 drivers championship, missing the top honor by two points. He won rookie of the year honors and won five out of ten races including the Watkins Glen Six Hours and finished on the podium three additional times. James Weaver was third in the championship, Rob Dyson fifth and Butch Leitzinger sixth in the points tally. The team won five races and were one-two twice.

The team ran a partial schedule of Grand-Am in 2005, running five races in partnership with Howard-Boss Motorsports. The driving trio of Rob Dyson, Chris Dyson and Harrison Brix drove the Pontiac/Crawford to a best finish of seventh at the Virginia International Raceway 400. The Dysons maintained that partnership with Howard-Boss Motorsports in 2006 and ran six Rolex races in the Crawford/Pontiac, starting with the Rolex 24 Hours. Rob and Chris Dyson along with Guy Smith had three top tens, including a seventh at Miami-Homestead. The Dysons ran six races again in 2007, including Rob's 18th Rolex 24 Hour in the Porsche-powered Crawford with Howard Motorsports, finishing a season best thirteenth at the Crown Royal 200 at the Glen.

The team returned to the Grand-Am series in 2010 in partnership with Godstone Ranch Motorsports at the Utah 250 in September. The #16 Heart Car of John McCutchen II and Davy Jones ran well and finished thirteenth in the Daytona Prototype class in the two-hour and forty-five minute race.

Rob Dyson: "We ran the Riley and Scotts for eight years. We have not run any other race car as long as we have those things. We had one chassis that had over 53,000 racing miles on it, including two Daytona 24 Hour wins in 1997 and 1999. The Riley was the most successful car we ran. We ran it the longest and won a bunch of championships with it. It was a magnificent car to drive: beautifully balanced, very stout, very forgiving, and an easy car to drive fast."

All told, the team's Riley and Scott MkIII cars claimed thirty-six victories with two overall and two class wins in the Daytona 24 Hours, between 1995 and 2002.
