In 2003, the race got more serious with BSA Racing entering a Radical SR3 and a Porsche 911 GT3 Cup with Wolf Henzler as its lead driver, while Amprex Motorsport entered the BMW M3 GT for Charles Kwan, Matthew Marsh and Genji Hashimoto. Alex Yoong was also back with Jaseri Racing. But in the end unfancied G1-Meritus won the race after outlasting its rivals, with Eric Yeo, Firhat Mohkzani and Chin Tzer-Jinn driving their Porsche 911 GT3 Cup car serenely to victory after completing 268 laps.
