Hey 45mph,

I drive a pro4 and have tried drifting it on cemented grain pebbled ground. It drifts well. The tiny pebbles helps make your ordinary rubber tires slip smoothly. No need to change your tires to ABS/PVC or some sort. If you want to make it more slippery, just wisk a few drops of water on the ground. That should make it better but harder to handle.
