I don't think the suspension design will give you the most out of coilovers.
Bump steer seems to affect me a lot on the hill i live halfway up on. When my rear tires clip a manhole recess in the asphalt, i get some bumpsteer, it may be due to the weight loading on the steep grade, but it is present.
Stiffer spring rates are also not the correct way to really get the car going left to right IMO. Proper damping (very possible with CO) and god sway bar loading are key I believe. I would definetly try SSEi sway bars (FE2/F41 suspension) on your car, I found them to help immensely in the corners. Pair this with new energy suspension poly-urethane endlinks, and see how you feel about it then.
