Ground Control not designed to improve handling??
I dont think they make them anymore. I called to ask about it, and they said they are discontinued.
I don't know who you talked to at GC, but I just got off the phone with them right now and they are currently out of stock and awaiting parts to replace them. They should be back up on the website in about 4 weeks or so. They are also rewriting the instructions for installation.
Copied from Joel -r post :
I looked at the Ground Control option too. Problem with that setup (if available) is that it's not really designed to improve handling per se, its purpose is to allow lowering. I'm not that interested in going lower unless it's specifically designed to help with handling without other side effects. I really think the Swift setup will be a nice balance between being stiffer, a bit lower, still comfortable & very daily drivable.

@ Joel R-
As for what you said about GC not designed for improving handling, then I wonder why they use Eibach springs with a specific stiffness (+20-25% stiffness with off the shelf springs) over stock springs? And guess what GC allows you to do? Custom spring rates also! I have used GC coilover systems in 3 different cars with all positive aspects of an increase in handling prowness all proven in autocross on all 3 of my vehicles plus over many years of daily driving. All this for a very affordable price and made in the USA.
And they also allow the option to lower your vehicle too which you stated. I understand you are doing a great thing for the Insight community with Swift springs, but there is no need to try to tarnish the image of GC or downplay what they have been doing in the suspension world for many years, far longer than Swift.
