The WL Toys 284131 (which I reviewed here) and the K989 that precedes is described as a micro drift car but the lack of gyro (such as appears standard in the SG1603 drifter) makes this difficult. In this article I've installed a gyro, added a low friction aluminium wheel and tyre set and have improved steering lock which vastly improves the drifting experience.
Drift wheels and tyres
The 284131 and of course the K989/969 which is it is based on have and excellent weight balance and handle well which makes them great grip/track driving micro rc cars but no so good for drifting. First of all let's address the wheels - the stock tyres have too much traction so we need to swap these out for a set that have much less. Rather than messing about with trying to put PVC piping over the stock wheels you can change them out for a set of bold on aluminium drift wheels cheaply and easily with this part: Metal PO Fitting Wheels Hub Rims Tires with Drift Tire For Wltoys 1/28.
