Aero dynamic in such "small scale" is not going make that miuch different, the only thing it matter is the wheel base (how long and how wide). The shorter and skinner the car is, it will make it easier to drift sharp and quick corner, to make it simple
short wheel base = sharp and big movement
long wheel base = longer drift time and hold drift angle
narrow wheel = easier to slip (drift)
narrow wheel base = easy to shift body around/quick respond to steering
wide wheel base = keep minimum tarction/quick regain traction
