Roller

Rollers sit at the front, rear and sides of the car and roll along the track wall to steer it through corners. Larger diameters corner more steadily; smaller ones are lighter with less drag, and rollers with built-in ball bearings spin more freely. The whole car, rollers included, must stay within 105 mm wide.

For how each kind of part is used and tuned, see Tamiya Hong Kong's Mini 4WD setting guide (in Chinese).
