good books on suspension tuning

[hayesey]

over the past week, I've been attempting to deal with a company who are making me some front shock absorbers.  It has taught me that I know bugger all about suspension really.

So does anyone know of a good book on suspension tuning for track?  I'd like something aimed at amateurs, some maths is OK as long as it's not too bad, I'm not a mechanical engineer.
