Just to mention that i ordered a shock from Jason @ paragon-products last Thursday as i knew that the turn around time to get mine fixed by koni would be too long. I got it yesterday (super service from Jason btw).
Replaced the shock last night. Comparing the defunc shock with the new one revealed the following. They would both compress the same way but when i'd let go the rod, the new one would come up slowly while the defunc one would pop right back up.
Anyway, no more clunck clunk from the rear of the car and the handling feels way better too.
I'll now send my defunc one to koni.
