I second the swaybar recommendation.
Fred's book is a good one. I have read it several times. He also has a very good one on brakes (Carroll Smith says in one of his books there is no point for him to write a good book on brakes because Fred already did one!).
Once you read Fred's book, the definitive book on chassis is Milliken's "Race Car Vehicle Dynamics".
