Here are the calculations I ran for the Eibach bars as well. There is a lot more room to adjust the car into understeer but less margin to move into oversteer.
For the Stillen bars I would call them oversteer biased, for lack of a better term, and the Eibach's are about equal biased to dial in over and understeer. Both have 15 possible settings.
It should be noted the stiffness % over stock is much higher on the Eibach kit compared to the stillen bars, so the response and ride will be different.
