Lei Kit Meng competed in two races of the 1998 British Formula Three Championship for Carlin Motorsport.
In 2008 the team attempted to enter two cars for the World Touring Car Championship end-of-season round, the Race of Macau, with Lei Kit Meng driving a Toyota Altezza and Jo Merszei driving a Honda Civic Type-R.
However, the team were not allowed to compete after the scrutineers found their cars did not comply with FIA safety requirements.
On 18 November 2019, Lei Kit Meng, driving a Nissan GTR-34 in the Macau Touring Car Cup, hit the barrier at Mandarin bend.
Instead, he drove along the circuit for over one lap until the race direction showed him the black flag to disqualify him and order his immediate return to the pits.
