the base stiff lipo chassis that ships with the current batch of cars is VERY good. it works on carpet and asphalt (both with rubber tires). if you look where the car 'drags' on the track you can think about places on that chassis that it might make sense to 'self-optimize' the chassis with a Dremel and cut-off wheel.
this is one of the more extreme narrowing that i've seen. prior to this, Martin Crisp had done something as dramatic as this. it sure does make mounting electronics a little more difficult though...
