I just realized that this was still saved as a draft. As I've the springs on the car for 6 months I figured I had best finish and post this.
Stiffness 480 lb/in
Free length 9"
I don't find the springs overly stiff unless I'm on the roughest of roads. The car has minimal body roll compared to the stock springs, but when you consider a 320% increase in stiffness minimum what could be expected. The paint has been holding up nicely after a year. No signs of rust. Length wise they are about the same length as a preloaded but not installed spring. Although I have adjustable seats on my shocks I don't believe I adjusted them from the position where I had the stock springs mounted. I know on the GT6 on Spax fixed seat springs you will need a 1/2" spacer but Spitfire drivers will most likely be alright.
