Just went through the spring swap saga. First get underneath and feel around the bottom of the front spring pocket. Make sure the end of the coil covers only one drain hole. You'll see two of them. You can actually see the low point of the spring pocket from the shape of the outside (protrudes slightly). Shine a light up into pocket and check if locator prongs can be seen around inside radius of spring top.
I was missing at least an inch of drop when the Hotchkis springs replaced the 9C1s. I loosened the upper and lower control arm pivot bolts and found out where that other inch was hiding. I loosened the pivot fasteners with car on Rhino ramps. Car needs to settle a little on its own weight before tightening up bolts again. The shorter springs force the arms to find their new normal angle. Otherwise, the suspension is bound at the old normal ride height.
Since you're saying the Eibachs made your car higher, I'd say either, 1)pull them and count the prongs before the springs go in. Once they're in, make sure you count that many prongs. Or, 2)shine a flashlight up there and try to visually determine that the spring is sitting squarely in upper pocket outside the prongs. That's all I can think of. If it means anything, I feel your pain. Hang in there. Between a manual, this forum and yourself, you'll figure it out. Hope this helps.
