> I'm betting that the Viggen springs with Konis is a nice combo.
For reference the Viggen dampers versus Koni on the bump stroke they are valved more or less the same (Koni is a little stiffer). On the other hand on the rebound stroke the Viggen damper is something like 30% faster (less stiff) than the Viggen damper bump stroke. The Koni is the identical (bump / rebound) on full soft.
Bump stroke valving is determined by the unsprung weight. The rebound valving is set by the stiffness of the springs, per Koni.
After running a set of Koni dampers on the rear of my Viggen I pulled them and put the stock dampers back on the car. The reason? I never could find a setting for the Koni which proper damped the rear suspension (critical damping).
Before I ordered the Koni rear dampers I discussed the Viggen spring rates with one of Koni’s application engineers. Basically he told me not to fit their standard 9-3 dampers to the car without revalving for the Viggen. The charge is $95 per damper and there is no guarantee that you will guess the correct valve on the first try. Koni wouldn't (without the car) recommend the change in valving. Thus I guess the guy at Koni gets an “I told you so”.
I would also note that the stock Viggen dampers are really made nice (perhaps better than Koni).
P.S.
How could you possibly run the rear dampers at full stiff? What occurs is what is called "pump up". The rebound stroke is so slow that with multiple bumps the car will sag close to the ground. Note that some people do this to generate oversteer if they have no other means of tuning the car.
