Thanks for your reply. At this point I have to apologies for my limited english (it starts to end when it becomes technical)...

I have pretty good damper/spring set (Koni/HR) and a Wiechers Strut Bar. Soon I will start to overhaul the whole front axle and I was wondering if the "Stabilizer front axle" (sorry google translator) is still available for the MK4 ?
(I have some pictures from a MK5 - but can't upload them here).
