A fantastic book on the subject, without getting too technical, is:
"How to Build And Modify Sportscar And Kit Car Suspension And Brakes" by Des Hammill.
It's by Veloce Publishing, ISBN1-903706-73-4. Ensure you get the latest edition (I have 2nd edition).
It's aimed at Kit Cars and Clubmans, but will really help anyone understand their suspension better, and appreciate what compromises the designers of road cars must make.
