While I don't have an Avant, I'll somewhat 2nd what Neil's said about Koni's as I've certainly been annoyed with mine as well.

Koni touts their shocks for our cars as "adjustable" but that comes with some caveats. As mentioned, they're top mount adjustable so they have to be removed from the vehicle to be adjusted. But it goes further than this. To adjust them, you must first secure the shock body and then completely depress the shock into the housing in order to 'activate' the dampening adjuster, so to speak.

But even more ridiculous this? There is no click setting or indicator of what the current level of adjustment is or how much has been made. So you're totally flying blind. Had I realized THAT part, I never ever would have bought them. Pics of said adjustment here.

It's obvious that their shock was designed to be adjusted while on the vehicle. This way, one could both see what the level of adjustment is (using a knob of some kind). But more importantly than this, the weight of the vehicle on the shock would obviously be compressing making it far easier to adjust. Not a bad shock, just bad parameters around it.

Unless dampening adjustment is done using a click set method with a remote... I would highly suggest skipping on that shock on CO.

Bische, my suggestion would be to just spend a few hundred more and buy a set of coilovers. You might be able to find a spring / shock to match your preference but IMO a coilover that comes pre-dampened (with a shock/spring unit) is a far better option. I went Vogtland as they are slightly more stiff than OEM sport and offer the far easier rear adjustment style. That and everyone who runs them seems to have undying adoration for them... not something you hear about shock / spring combos 99% of the time.

Many perceive CO's to only be about gettin more low, but in actuality they provide a matched shock and spring with the added bonus of height (and possibly dampening) adjust-ability.

A while ago, Eric / EBG 1.8T put together this ridiculously phenomenal guide to CO's. While the prices have changed, 99% of the data has not. Check it out...
