The 1999 / 2000 season saw the collaboration with Opel South Africa, which led to the team’s participation in the South African Touring Car Championship (SATCC) under the name of TEAM PETRONAS SYNTIUM OPEL. When the South African Touring Car Championship ceased, the team's South African challenge continued with the 2001 South African Wesbank V8 Championship with a completely new car, which was designed and built in nine weeks.
In 2002, the team entered the prestigious world of touring car when it entered what is arguably the world’s premier touring car series, the British Touring Car Championship (BTCC) series under a new name PETRONAS SYNTIUM PROTON.
The team entered a new phase with its new liveries as PETRONAS SYNTIUM PROTON when the team competed with two PETRONAS-backed Proton Impians in the BTCC Drivers' and Manufacturers' Championship, adding a brand new marquee to the grid in the 2002, 2003 and 2004 season.
After a three-year campaign in the BTCC, team PSP returned to Asia in 2005 to begin its challenge in the Asian Touring Car Championship (ATCC). An FIA-sanctioned race, the ATCC is held as part of the Asian Festival of Speed (AFOS) with rounds across Asia. BTCC pilot Fariqe Hairuman returned to his seat in the Proton Impian partnered by seasoned Team PETRONAS driver Mashlino Buang to lead the team’s charge in the Division One category (1600 cc and above).
Participating in Division 2 (1600 cc and below) Mohd Syahrizal completed the team’s line-up for the season. The season ended on a high note with Team PSP drivers Fariqe and Mashlino claiming second and third overall in the drivers’ championship for Division 1, while Syahrizal took second overall in Division 2.
