Hi, the cusco struts are much stiffer than stock (and kyb GR2).
They are 40 way adjustable and setting them all the way stiff is just back breaking stiff (handles amazing).
I usually run them between 5-10 clicks from full soft.
The rallitek overload springs and the cusco struts are a good match and gives a sporty ride (handles way better than stock even with the lift). There is good suspension travel without any unwanted bounce or sway. I pretty much just plow through anything.
