Theory Section (Suspension Set Up)
Introduction
Summary of the Suspension Set Up Ideas Presented
Weight Transfer - page 1 
Introduces concept of relative wheel pair stiffness. What is "wedge"?.
Examples are weight transfer example and shock example.
Weight Transfer - page 2
Total weight transfer.
Rotations About the Yaw Axis
We look at some of the contributors to oversteer & understeer as moments
tending to rotate the car around a vertical axis through the centre of gravity.
Shock Absorber Tuning 
We cover shock absorber tuning for response to driver inputs, control of the chassis platform, and tyre compliance with the road - all well accepted aims
of shock tuning.  But is it possible to using shock tuning for balance? We
discuss and develop the guiding principle you might use to dial in more understeer or oversteer with shocks. 
The Neil Roberts Article on Shock Tuning for Balance
Steering Geometry Article from Grass Roots Magazine
A "Mindset" for Analysing Suspension Set Up Problems  
The relative importance of suspension geometry considerations and weight transfer.   We need a "mindset" on how we think systems work, so we can
improve them.

Development (of the Race Car)
Rebuilding the Race Car
Race car preperation - how your race can be won or lost in the workshop.
Springs, Anti-Roll Bars (and shocks)
We stress the importance of knowing, understanding and testing your
spring/anti-roll bar/shock combination.
Suspension Geometry
Workshop Set Up
What needs to be done before you get to the track
Track Testing
Skid Pad Testing
The 200 ft diameter steady state test as used in America.  Why don't we do this in Australia?
