I've spoken with a gentleman in tech support at Eibach several times now. He's very friendly and fairly helpful, but unfortunately, Eibach is really not much real help at this point. I continue to be told that they will bring in JGC with my same specs in a week or so to find out why the drop is not the same as the published data form their original test vehicle. However, we're going on the 4th week now with no actual vehicle acquired by them yet. Then whenever they get said vehicle and find out the spring specs are incorrect for my particular pkg, I'll likely have to wait for another several weeks or maybe even months for them to do all their R&D, testing and production scheduling before I can hope to see any replacement springs.
Therefore, the plan of action at this point that the tech and I agreed upon is to come up with a spring spacer to run on the bottom of the spring to achieve the desired ride height. The spring rates do not feel bad, so it's just a matter of height at this point.
Based on the information he had available (measurements, geometries, etc) he thinks a .5-.625 spacer should work in order to raise the front by roughly 1 inch... which is about where I think it should be. After a bit of digging and a phone call or two, it looks like I may have to make the appropriate spacers rather than buy them. There just isn't much out there with the dimensions I need... and if I want it to be right then I'm probably better off doing it myself anyway.
I guess I'm a bit disappointed with Eibach, not that I really expect better service regarding this particular application, but I've always had very good experiences with their products in the past... and there's no urgency on their end to resolve this. Again, the tech I'm dealing with is a good guy, but in the end I'm left to fix the issue myself. As a customer that just leaves a bad taste in my mouth.
I'll report back with results.
