KW2 or PSS9 or…

Now the PSS9 from Bilstein made me curious. At the moment I have a Seat Leon all-wheel with a H&R thread f. the TT in it and must say a great driving behavior, but it should be a bit tighter! That’s why I prefer something individually adjustable like the KW2 or PSS9! However, I don’t have the PSS9 going too deep for my little vehicles. Who has a PSS9 installed and can tell me if e is the TT quattro going deep enough and what is good?! Or rather the KW2 or something else????
