Why does Häns Racecraft not recommend off-set steering rack bushings?
Bump steer is a change in toe when a wheel traverses irregularities on the road surface. In order to minimize bump steer–a condition that can be caused by using shorter springs to lower a vehicle–some manufacturers offer offset steering rack bushings. These offset steering-rack bushings can rotate inside the housing and compound the problem of bump steer. Therefore, HR recommends center-drill bushings only for all applications.
