The feel of a steering wheel of a car depends on how the steering system is constructed. Recirculating ball is a good way to isolate the feel and rack & pinion is better at transmitting what front tires are doing. Add dampers (hydraulic, electric assist, or simply a "rag joint") will take away the feedback to some degree. Add steering by wire and I can't imagine how that feels; I read about "synthesized" feel but that can't be good.
The improvements to chassis rigidity and suspension setup (including alignment) affect the feel of the whole car while going through a corner, over a bump, or their combination.
