at Silverstone. During the off-season, Yoong took up mental and physical training with psychologists at the Bukit Jalil Sports Complex back in Malaysia. The training gave Yoong confidence when arriving back in England in 1998. Remaining with Portman Racing, the team was using Renault engines for their Dallara F397 and F398 chassis. Consistency brought Yoong results in the lower half of the top ten, which included two sixth places at Silverstone. Going into the round at Spa, Yoong switched to Alan Docking Racing. He had to adjust to the Mugen-Honda engine and came up with results very similar to Portman Racing. 1999 proved to be a watershed year. Yoong's sponsors dropped out, and his father was forced to fund his son's racing activities until the family became indebted. He missed the first two rounds of the year but made a strong comeback when he returned at Thruxton. Driving a Dallara F399 Mugen Honda, Yoong finished sixth, 11 seconds behind winner Jenson Button. He followed this strong finish with 5th at Brands Hatch, in a race that covered the top seven by 3.4 seconds.

He finished fifth. At the next round at Donington, Yoong ended up starting fifth and drove arguably the best race of his career. During the race that caused unpredictable conditions and other competitors spinning out, Yoong ended up second at the midpoint, two seconds behind leader Werner Lupberger. The pair pulled out a 22-second gap over the entire field. With the deployment of the safety car to clear several cars who had retired, Yoong was unable to see the safety car's lights in the spray. This mistake costed him eight seconds behind Lupberger, but Yoong set five consecutive fastest laps to catch up. Later in the race, while he was in fifth gear at 220 km/h, he aquaplaned and spun after
