The fourth round of the PEMKAR series took place on the 4th November at the Stadium RC Raceway. This time racing was run anti-clockwise in order to alter the track. With such blistering hot racing conditions most, if not all racers were encountering very high tyre wear as overheating became an ever growing problem.
Wirawan with his S411LE easily topped all three rounds of qualifying, claiming TQ going into the finals later that day. However due to heavy rain only one final was successfully run which was dominated by Wirawa allowing him to defend his 2011 championship title. This marks the first National level Championship win for Serpent in Brunei.
