A few years ago I read a document that was written by an American cornering school. It's use as the theory part of a race cornering course that they provided. Among other things it described very well how to enter corners with foresight about what is after the corner. For instance if you are coming into a series corners from a long straight, you would brake late. If it makes any difference it was a very long document. Had a few black an white pictures and on a basic website. Does this ring any bells, and does anyone have a link?
