Koni FSD or SSK?

[cherry1809]

Still gathering info and want to know the ride difference between these two kits.
I've been told some people find the SSK kit (With Koni springs) A bit too firm.
I had a ride in an SSK kitted 850 when I went to look at my new purchase, And found it perfick
Is the FSD being progressive the only difference between the two?

Have a look at this: http://www.koni.com/58.html

I have FSD's on mine, I find them really good, the car handles really well, and is smooth when you need it.

The ssk is excellent. You can set up the damping to what/how you like and take it from there. I have the 30mm Koni springs on mine and I find the ride quality no more worse/firm than the standard setup they replaced.
