One other thing, as well a taping up/removing mirrors tape up your speedo-you do not need to see how fast you are going-that way you can judge your corner entry speed by feel not some number on a dial.
Oh and if you are at Cadwell on Good Friday get WJB to show you round since he's
1/ good
2/ fast, and
3/needs the practice since we are racing there on the Sunday and Monday.........
