I am no expert in drifting (more of a newbie) but according to my personnal experience a lighter car is a lot easier to control the drift. You can make a heavy car drift with extra power but it is a lot harder to control...
I drift with either my Nitro RS4 18ss or with my Electric sedan. I use both drift hard rubber tire or ABS pipe.
The Electric is an old Kyosho TF-2 carbon fiber chassis with Novak sport ESC and 13T motor. It is significantly lighter than the RS4 and is a lot easier to control drifts. It will drift well on the drift tires or the ABS although ABS is like driving on ice. ABS will allow you to drift at low speed.
This statement is made only according to my personnaly limited experience. Please feel free to correct me if I am wrong and to give us all tricks to improve our drifting abilities.
