Clocking Koni Shocks

Prior to having the Koni rear shocks installed, I was going to have them dyno'd. Then I realized that I probably won't go through the motions of testing, removing,testing, etc. I just wanted to make sure that they both were doing the same amount of work. So after setting both to wide open, I measured the time it took to go from fully compressed to fully extended. That was about 9 seconds.
Then I started turning up the rebound on one till I got to about 15 seconds. That was about 1.25 turns on that one.
On the second one, it was about 1.5 turns.
I realize that these times are dependent on the gas temperature at the time. It seemed to work for my purposes though.
After installation I noticed a lot of thumping from the rear. After I got home I did some checking and found that the bottom cross bolts were not very tight. They were only about half as tight as what they should have been (115NM). A little torque wrench work and all seems well now.

I have to preface my answer with the fact that the front struts have 31k miles on them.
The car is a little unbalanced due to the front still having more compression damping than rear. There seems to be a little more willingness for the front to side step some when you corner in a turn with some ripples in the pavement.
The rear seems even more planted now. You can definitely feel the back being more compliant. Hence more grip.
Nothing scary, just different.
Your description sounds like the way my car felt before I replaced the shocks at 46k. It tended to skitter over bumps around corners. It's definitely feels more "planted" now.
