I am uncertain that bump steer causes any significant "problems" grip wise, other then the car wants to take a different path while the suspension vertically cycles thru a bump. as a driver that is always undesired/ a pain/distraction, etc, but not sure its a real issue at anything say below 7/10ths driving. Likely a subjective quality at modest levels.The normal corrective action/remedies changing the height relationship between the inner LCA pivot/outer lower ball joint, as it relates to the the inner and outer tie rod assembly. The change is normally is made by n adjusting the height of the outer TIE rod. It is doable, just not sure how close to perfect one needs to achieve (and perfect is not achievable in most cases).
Bump steeri s effectively a toe change thru vertical travel of the suspension
