Im running stanza struts so im not sure about escort struts but im running 4 degs castor (lots, u can see it straight away when u look at the struts) and its fine on the road, the stearings still light and its way more stable at high speeds. If its a real problem cant u adjust the tops and the bottoms to compensate, thats what i had to do to achieve the camber and castor i wanted. also what about using different castor rods?
