What you are adjusting with the white shims is the static, or un-compressed caster.
Sorry to bring back an old post, but i just read from this site (
http://wcrccc.v21hosting.co.uk/setup%20theory.htm) it says:
Also, the bigger he caster angle, the bigger the camber difference induced when the wheels are steered. This camber difference is to compensate for the chassis roll and tire squirm when the car is cornering. Hence, a lot of caster will provide more steering in high-speed corners, where chassis roll is more pronounced, and whilst turning in. It will also make the car more stable in rough conditions, and the car's straight-line stabili ty will also be improved. A small caster angle will provide more steering in low-speed corners, and less turn-in.
So my understanding is, castor will give you more camber in high speed corner and help steering
So with the 10 degree blocks, the castor DECREASE at high speed corner so it should mean turn-in progressively softer not harder?
I'm confused now
