Unsprung weight

In order to get an estimate of the chassis unsprung weight, I weighted some parts. First I tried to put the wheel on a scale with the push rod disconnected but the result was a bit off (~18kg for the fronts). To be sure I weighted most of the parts individually instead.

Front

Upright + AP caliper + disc + hub assembly: ~10 450g
Wing: 1 725g (incl wingstays etc)
Wheel nuts: 202g
Wheel: 9 360g (Force Racing 7"x 13" with half worn Dunlop slick)
Damper: ? (Bilstein Race)
Push rod: ? (steel)
Rocker: ? (aluminium)
A arms: ?

Sum: ~21 737g + ????

Rear

Hub carrier: 3 595g
Caliper mount: 823g incl fittings
Pads: 369g
Caliper: 1 440g incl fluid and hose
Brake disc + hub: ~5 400g
Wheel nuts: 200g
Half shaft: ~3 000g (unsprung part only)
Wheel: ~10 800g (Force Racing 9"x 13" with half worn Dunlop slick)
Damper: 2 401g incl spring and everything else (Bilstein Race)
A arms: ?

Sum: ~28 028g + ?
