Victor, I'm planning to get a set of these when the $$ is right. I had a few questions...
What is the purpose of the 2 parts to the springs? The red/black parts... Different rates?
I tried putting a set of eibachs on my Z, but due to my subs in the back, the rear set couldn't handle the additional weight. Will these have the same problem, or how could I adjust it to prevent this from happening? If that is possible, then more power to these!
Also, is there anything in the works for an automatic controller like the Tein EDFC? Not completely important, but still a nice feature if possible...
Looking forward to your review!
