I believe the best book out there for car set-up is "Tune To Win" by Carroll Smith, published by Aero Publishers in California. Smith is a former F-1 team manager and designer; his discussion of handling, particularly roll centers, is definitive. It covers everything from wings to tyres. I've seen more than one pro R/C driver with this book.
It's not stocked by many book stores, but it can be ordered. I don't know about the on-line sellers.
