You are into one of those areas where ordinary car mechanics are typically not up to the task. They are used to setting things back to the way they left the factory. ... Your car likely needs a race car or custom hodrod mechanic. You need someone who can look at what you've got, drive the car and determine whether the symptom is coming from a worn part, an incorrect part, or the design and layout of the suspension. As several other people mentioned, I too have a car with very quick turning response. The original builder wanted that because it was built as a dedicated race car. It took some time to get used to it, but I like it now. ... But it doesn't change directions just because I hit a bump (bump steer). You need to find out from someone who knows race cars whether your car was built wrong or was just built to provide very quick steering response.
