Lots of stickers and the car has to be a TOTAL piece of shit. Preferrably it should leak oil uncontrollably, smoke, cut-out randomly, and have wires hanging all over the place. When in doubt with wiring use the house style twist-connectors, those are rad for drifting. Also every single piece of bodywork MUST be held on with zip-ties. If not your ride will never be "drift ready"...
