    Weight ~3,900 pounds.

    Weight distribution, 64/36

    ~1,400 pounds on the rear springs.

    Not sure the spring rates are listed anywhere.

    Air ditched spring weight? The spring rate of the helper springs on conversion shocks? Who knows. I'm sure it's different for each manufacturer.

    Weight with half and full tank? ...You're kidding, right?

    If you really need/want to know, have the car weighed on 4 pad scale.

    Why?

    I thought about that when I first read this question, but had no answer. Where in the world did you come up with that MC?

    Re: how much weight is on rear suspension 93-02 Eldo & coil spring rates?

    Thanks, MC. I am working on a performance spring swap. Best I can tell, 97-04 Mustang front coils will work. 1895 lbs. on front wheels. I'll need to cut one or two coils off because they are a bit taller.
    The extra 500 lbs. on the V8 Mustang front wheels effect the spring rate selection. However the weight of the V6 Stang would be closer. And due to the location of the Eldo gas tank being just forward of the rear suspension, the amount of gas (at an average of 6.25 lbs. per gallon ) will also offset 50-100 lbs. of the weight difference. And relocating the battery to the trunk to help the weight distribution will also offset another 45 lbs.
    Once the right Mustang front spring is selected and the air shocks are nolonger needed, I can focus on finding good road racing rear shocks

    Thank you! That is the exact chart I have been looking for.

    ----------

    Using the chart, I see that the ETC spring rate is 279. I also found compatible springs with rates over 450 lbs.
