I'm no expert but it depends on motion ratio of the suspension, sprung mass supported by each wheel, the desired ride frequency and as a result spring rates and probably many other factors so ideally You'll need suspension position sensors to find out - my point was only to question the feel of rock solid setup. As for the rebound setting (I guess spax are 1 way adjustable so rebound only, may also affect compression as well), frankly I seriously doubt that each of 28 clicks actually does what it's supposed to (Bilstein offers 10-step single adjustability as well as AST, cheap makes often offers twice that much; had once low budget - about the price of Spax - twin tube TEIN SS with 20 clicks or so on WRX STi, You could barely feel any difference between 3-4 clicks at a time, when set up for stock ride hight shocks were bottoming out because of very little oil in it). After reading more about suspension I wouldn't buy coilovers again without a dyno plot of each shock (including plot of each adjuster position). To sum up, I would prefer non-adjustable Bilstein over spax for similar price but each on his own and as long You're happy with your setup that's all that matters I suppose
The handling is great with the spax coilovers. Actually a very nice bit of kit! The dampening is easy to adjust and i would disagree. You can feel change with just a couple of clicks each way. I'm running 23 up front, 25 rear and it's unbelievable how flat the car corners. Very happy myself and i think anyone who purchased them for their Clio would be more than happy too.
