IMSA GTO 1993
The car was originally constructed and campaigned by Riggins Engineering to compete in the GTO class of the 1993 IMSA Camel GT series, piloted by Joe Pezza.  The team won the Portland, Phoenix rounds and finished second at Road America that year and finished the year 3rd in the GTO points championship.  The following year, Tommy Riggins ran a partial schedule in the car, winning Portland and finished second at Laguna Seca.  Following that season, the car appeared in various IMSA and SCCA events as Tommy Riggins' "house car", including the rain-soaked Daytona IMSA Finale in 1996.  Following that, the car was primarily rented out for SCCA club events until being purchased by Brutal Performance in late 2000. 
Grand-Am Rolex Sportscar Series, AGT 2001

Brutal Performance updated the car to fit Grand American Rolex Sportscar Series AGT class rules (rear wing, air jacks, chassis updates) and showed up at the 2001 Daytona 24 Hour test days, putting down the 3rd quickest time in AGT.  However, the team was unable to secure a deal to run the Rolex 24, continuing to develop the car before reappearing at the 2001 Grand-Am finale at Daytona where the team finished 3rd.
Today

In 2003, after being legislated out of the Grand American series by rules changes, the team began campaigning in Historic Sportscar Racing's Rolex Endurance Series, winning a class points championship that year.  2004 and 2005 saw the team with top five finishes and podium finishes at the Daytona finale of 2005.
