Hmmm okay. I'll have to see how to get the weights for a couple of these parts. The rotors/wheels/tires are easy. The rest I'll have to dig a bit. Thanks again Gomer.

Take the wheel assembly off and weigh that. Take the damper and spring assembly out and weigh that. Then, use a bathroom scale to weight the unsupported suspension parts left on the car. you want to hit the scale at close to full droop to make sure most of the suspension is supported by the scale.

It won't be as accurate as weighing off the car, but we are talking a pretty minor margin of error difference.
