Shock positioning?

Shock positioning?
I have a question that I am sure people have talked about before. What is the effect of the shocks when placing them in different holes on the shock towers? I know that this plays a factor on how the car’s shocks work, but how? I have attached a picture with numbers on the shock tower. Can some one please explain this by numbers. The stock place on this car is the fourth hole.
Thanks

The more upright the shocks (i.e. hole 5) the stiffer the suspention. The more the shocks are layed down, the softer the suspention.

that's true

This is looking much clearer...The shock act Lazy? What does that mean?

Leaning over shocks
I have always thought of it , as an effect on the progressive nature of the shock.
If you lean over the top of your shock on a touring car your will gain mechanical grip in the long sweeping corners due to making the shock initially softer in the first part of it's stroke before the suspension stifftens up. The cars weight is allowed to roll and put pressure on the outside tyres more.
However leaning over your shock too far would make the the shocks sluggish to react into chicanes where you want the car to roll from side to side quickly.
As always it's a trade off.
Best thing to do on your car is to try both extremes on a track that has both fast & slow bends and also a chicane.
Get to know how the car feels at both extremes, don't forget to re-set your ride height each time.

Bad example:
Strap on some roller stakes with no suspension and really hard wheels (like if your shocks are upright). Go full speed and turn. You going to spin/slide out and fall...now strap on some skates with rubber tires and suspension(shocks layed down). Go full speed and turn. The tires will side-roll and the suspension will compress before you slide giving you more time to balance.
It's all about balance on these cars...

This type of setup is generally not good for bumpy surfaces. However, I've found that using stiffer springs that are more layed down can get rid of traction rolling without having to soften the springs up and loose corner speed. The stiff progressive rate spring setup will let the shocks soak up initial steering inputs that can cause traction rolling, but the springs will tighten up nicely and keep the car from rolling too much and losing corner speed, especially in fast sweeping corners. This is assuming that you have already tried to get rid of traction rolling by using minimum ride height, a low center of gravity (and truing tires to a smaller diameter if you're running foams).

More upright-softer
More inclinded- harder
Go to the track and try it!

It's probably why he put the sneaky face after his statement

I've always found from experience on the track that having the shock more upright is more 'stable' and laid down seems to give you less grip (rear), steering (front) forgetting the words harder and softer etc

Whats you theroy behind it then? The hudy set up book says its the other way round so thats correct?
