Well I've only driven the car hard in the twistys once since my alignment was completed, I keep starting the next project on my list rather than drive the thing lately. As I recall the previous set-up was slightly twitchy when turning on uneven ground. My last drive out with the new set-up was a big difference mostly from the addition of negative camber and a good alignment, turn in was amazing on tight low speed corners, the car rotated as if on rails. I didn't notice the wheel being twitchy and as a result didn't have to white knuckle grip the wheel. I initially just bought the bump steer spacers to gain back proper geometry of the FCA's. With the car being as low as it is the control arms were totally horizontal, the spacers give back a better angle closer to the factory design and eliminating the bump steer problems that can arise from being lowered.
