One of the best ways to learn to drive hard is to drive a loose kart. The best way to do that was a wet track, the best way now is a polished track. This was a short indoor track for the kids with the red karts. Now it's called the drift track and thanks to it my 10 year old has cut his lap times just over a second.
It may look easy but trust me .............. it just looks that way. My 10 year old has been karting for 3 years and has several hundred laps under his belt on the large track. Today was his first laps on the polished track.
