The tamiya tt01 was is a great car. But if you want an adjustable car to set camber, toe, droop, caster, ride hieght, etc ect. Go for a Sprint 2, Cyclone, or TC4. That way you can learn and see how small changes affect the cars handling and over all performance. I drive a sprint 2 and I LOVE it to death. Wouldn't trade it for anything in the world. Alot of my friends drive cyclones also. But its up to you between belt or shaft.
