I have some dyno plots of the rear 986 Koni sports. Not quite as digressive looking as I was hoping to see, but I'll bet they're going to work very nicely. Would be interesting to compare it against a 986 FSD shock dyno plot, if anyone could muster one of those.
(I had to return the first set of Koni sport rears for exchange, due to unbalanced compression valving left to right. Koni made good on it and sent me the new replacements along with individually tested dyno plots.)
I'm not really sure what you're asking about with the bump stops. But these 986 bump stops are rather long/tall and engage early, giving basically a progressive rate spring.
