Get a tamiya tt or tb series get the drift versions so you get the extras you will need.
Both chassis are built solid and have some adjustment the tb being better than the tt bear in mind.

Ive drifted with both belt and shaft driven and i still say shaft for drifting it gives instant torque unlike belt drive which spools up ie better for racing and in the corners etc

Everyone praises the sprint2 too for drifting never used one myself but they seem popular at our track.
