The team's racing interest went across the Atlantic for 2003 as the team entered the British Formula 3 Championship. The team performed well in their début season, with Piquet Jr. taking six wins over the year with a further five podiums brought his points tally to 231 points, putting him third in the final standings for the Drivers' Championship behind Alan van der Merwe and Jamie Green. The team's racing involvement was split in 2004 with the team entering Piquet Jr. for a second season in the British championship while bringing their attention back to the South American championship, entering fellow Brazilian Alexandre Sarnes Negrão. Both Piquet and Negrão took their respective championship crowns, taking a total of sixteen wins between them. The team graduated into the newly formed GP2 series, which replaced Formula 3000 as the feeder series of Formula One. The team entered their two champions Piquet Jr. and Negrão for their debut season in the category. British team HiTech Racing formed an association with the team's GP2 activities but this was terminated midway through 2005. The team finished sixth in their debut season with Piquet scoring a single win at Spa-Francorchamps.  2006 saw Piquet produce their most competitive season to date, with the Piquet Jr. taking four wins and challenging Lewis Hamilton to that year's title. The Brazilian, however, lost out by twelve points to the Brit and the team also lost out to Hamilton's ART Grand Prix team in the Teams' Championship. Piquet Jr. left the squad at the end of 2006 to join Renault Formula One team as the team's test driver. Piquet Sports merged with GP Racing ahead of the 2007 season to create "Minardi by Piquet Sports". Spaniard Roldán Rodríguez was employed to replace Piquet, Jr. The newly named team enjoyed little, if any, success in 2007 GP2 Series season with Negrão failing to take the mantle of team leader and only scored a single podium position. The team finished the year with 22 points and outside the top ten in the Teams' Championship. In the Euro Series 3000 GP Racing won both the drivers and teams championship both with Davide Rigon and Diego Nunes completing a championship 1-2. For 2008, the Minardi name was dropped from the team's title. 2008 saw the team gain some success, with Italian Marco Bonanomi taking a win in the newly formed Asia series and new signing Pastor Maldonado, winner of the previous season's race in Monaco, taking the team's first pole position in the series at the opening round in Catalunya.  2008 would be the team's final year in the Euro Series 3000.
