Reply per Matts formula. I removed the front bump stops, as it sits on them at ride height, which would change the spring rates. I then took off the limit straps and took the front coilovers off the mounts to let them extend. Took the unsprung measurements. Rear, just had to take off the limit strap and could pick it up enough on the lift to take all pressure off the tender coils. Here are the results.
Now I have double the numbers, and double the confusion :****:
Left Front
T - 14 - 10.0625 = 3.9375 x 125 = 492.19
B - 13.9375 - 11.1875 = 2.75 x 150 = 412.5
492.19 + 412.5 = 904.69 / 2 = 452.345
Right Front
T - 13.75 - 9.5 = 4.25 x 125 = 531.25
B - 13.9375 - 10.75 = 3.1875 x 150 = 478.125
531.25 + 478.125 = 1,009.375 / 2 = 504.6875
Left rear
T - 13.875 - 12.625 = 1.25 x 125 = 156.25
B - 13.75 - 12.5 = 1.25 x 125 = 156.25
156.25 + 156.25 = 312.5 / 2 = 156.25
Right rear
T - 13.625 - 11.5625 = 2.0625 x 125 = 257.81
B - 13.875 - 12.25 = 1.625 x 125 = 203.125
257.81 + 203.125 = 460.935 / 2 = 230.4675
