Sometimes it's better to forget all theoretic story's and make a set-up that you feel as good.
You need a day at a circuit, because on open road it's a not done
Because of use different materials (tires/springs) advice is difficult to get.
My experience so far is the more wedge the better.
I don't want the car to high at the rear, but driving is better if it is higher at the back.
I still need a harder compound tire at the back for best perfomance, but I am almost satisfied with roadhandling for open road.
