Here is my 2 cents. Remove the shocks and springs. Lower the frame to the ride height that you want. Measure the distance from the lower shock mount to the top shock mount. When the shock length is correct you will have 60% of the shock travel available for compression and 40% for extension. The second part is to match the spring length to the shock length. You want to run as long a spring as possible while being able to adjust the spring to the correct compression to set the car at the correct ride height. If the spring is too long you won't be able to compress it far enough to get the spring set nut and lock nut on. Too short and you can have coil bind. Have fun! John
