Four link suspension

[Brad Grant]

I deal with a number of classes of motor sport that use solid axle rear suspenion systems with four trailing links and a watts linkage or panhard rod. I have read many books on the subject but none have ever fully explained how changing the pick up points on the diff or chasis or diff nose angle affects the load applied to the tyres. Obviously all books talk about anti-squat geometry and always express it in terms of a percentage from centre of gravity.
If anyone knows of a particularly good suspension engineering book on the subject or better still does knows exactly how it all works then please reply.
