Thanks Ron, that's the info I was looking for. I think that will help other E92 owners decide which springs they want to get.
I think I'll end up just installing the Koni FSD since the Sports will lower my car too much for my dang driveway.
I contacted Ground Control yesterday and they're working on a coil over kit for the E92. He mentioned they should have a kit ready in a month or so. The reason for the Ground Control kit is they use Eibach springs and you can adjust the drop from 0" to around 2". Perfect for me since I wouldn't have to drop the car to get stiffer springs.
I ordered the Koni FSD/Eibach Pro-kit kit so hopefully I can sell the springs.
