The seven-turn 1.9km street circuit runs in an anti-clockwise direction and features widths of up to three lanes for many sections of the track - providing drivers with more overtaking opportunities.
The first race of the day saw an eventful start as the green flag came down for the Sporting Class, but a squabble at the front for the first corner - a tight 90-degree left-hander, caused an accident that required a restart of the race.
Patrick braked late pushing Brendan forward towards the outside wall. Meanwhile, Ken Foo in Car 10 tried to slip behind Brendan but unfortunately collided with Patrick, squashing him into the inside wall and forcing him to retire from the remainder of the race, while Brendan and Ken managed to escape severe damages to continue racing.
Upon the restart, Brendan lost the lead at the first turn to Wong Chin Eeg of Hiewa Racing Team in Car 5, who managed to lead the way till the chequered flag, taking 25 minutes and 17.374 seconds to complete 17 laps with his fastest lap-time of 1 minute 19.646 seconds.
After 1.702 seconds later, it was Kenneth Koh of Panglima City Racing Team in Car 28 who crossed the finish line for third position.
The next race saw droplets of rain beginning to fall as the Promotional Class racers lined up on the grid and as the racing intensity increased, so did the precipitation with some of the drivers seen experiencing difficulties with the greasy conditions as some spun at the hairpin section.
But as quickly as the rain began, so too was the sun to emerge and the conditions proved a little more tricky for the drives to contend with, prompting the safety car to emerge for three laps, while Shawn Lee in Car 6 lead the pack.
After 20 laps, Shawn finished the race with a 5.268-second gap to second place finisher Shukri Yahaya in Car 24 who was followed by Danny Koo in Car 23 for third a further 25.809 seconds later.
Although the Super Sporting Class got off to a clean start with everyone managing to get through the first turn, there was almost a pile-up right after along the long straight that forced Danny Koo in Car 23 to retire due to heavy damages.
The rest of the race proved uneventful due to the wet conditions with lots of standing water along certain sections of the circuit that made over-taking impossible.
The final race of the first day ended with Ho taking first place, followed by second place finisher Wong Yew Choong of ST Wangan Racing Team in Car 21 just 0.735 seconds later, while Syafiq bin Ali of M7 Racing Team in Car 7 took third a further 1.461 seconds later.
The second day of racing will see the top six racers reverse their positions making Keifli Othman of Team Laser Motor Racing in Car 63 starting in pole position with popular favourite Tengku Djan Ley of Team Nanoplus in Car 12 beside him. Although the weather is expected to be hot and sunny on Saturday, a thunderstorm is expected somtime in the afternoon.
