Will, without question the best option for astro will be a mid motor, and right now the best performing car out of the box is the Yokomo BMAX2 MR. Really solidly built and fantastic performer, cheap parts too.

No messing about, you build it as per the kit, and it works. I just changed the front springs for a harder set for my preference.
