Weighed my car today

Just curious on these items they are pretty heavy:
Sway bars? with size
Torsion bar size
Brake type/size/model front and rear
Stock or aftermarket bucket seats

71-70 dusters can be pretty light. They don’t have much trim, plastic grilles, no roll down window mechanisms, no tail light trim, no valence panels
Only a front sway bar, It’s a QA1 1 1/4”, PST 1.03 torsion bars, 73+ front discs, terrible Right Stuff rear discs (11” rotors), and Procar bucket seats. The seats are pretty light.
