Thats a shame to hear about that on the FSDs, I am about to buy them for our 4 wheel jelly mobile (Stilo) as its needs some and I'd like to see how they work on that car before going the more normal route on my GT as I want more comfort for the daily grind even if it is at the expense of outright performance.
Interesting little report of the FSD here

versus stock, koni yellows (on soft) and FSDs.
Having had Koni before on my Coupe when new the rear fully soft was pretty hard and I barely knocked up the fronts either so these FSD could be pretty good.
