There are a few comp for drifting in singapore.
one of them is Autodrift (monthly thing)another is Street Revo (sometime).
these 2 are of the more offical type of comp they are organising.
other than that some time will have comp from sch, RC communittee from house estate etc.
Currently offical to join offical comp stated above will be yokomo, enroute and MST.
Do take note that Yokomo kit will need to have a offical sticker on the chassis in order to use for their comp. This sticker thing only from Autodrift or their boss in KL Hobby Haven and the rest are their distributor etc ........
