Slinger Superspeedway

A high banked 0.25 mile oval, claimed to be the fastest quarter mile oval in the US, with a lap record of 11.095s at the beginning of 2005.

The circuit was founded in 1948 as a clay oval, and stayed that way until 1973, when it was rebuilt as an asphalt oval with high banked corners, the banking reaching 33 degrees.
