Hi all, thanks for comments so far. Scorpione Abarth Parts has told me that the Koni black and Koni red shocks are the same. Can anyone confirm this? They also say that the red ones are NLA, as I suspected. I thought that the black ones were weaker than the red. And there are Koni Yellow shocks too (not sure if ever made for a 600). I already have a set of front and rear black Konis, so maybe I am okay. I guess I could dig out my shocks and check out the numbers on them. I wonder if the red and black ones used a different part number?
Another option I suppose would be to try the black ones out, and if absolutely unsatisfactory for my driving style, send them to Koni and get them revalved.
