Feels puny compared to the recent suspension discussion, but I put on Koni Special Active shocks and struts, with new mounts front and rear and new strut bearings, plus some greasable Energy Suspension sway bar bushings on the rear while I was at it.
Because I'm slow and have limited car work time, I installed the shocks a week ago and the struts this weekend. New rear Konis and tired factory struts were a little squirrelly for the week in between!
I'd run those Konis (under the previous FSD branding) on my E46 330i and liked them. With admittedly only short around-town drives so far, I'm equally pleased with them on the GTI. Reasonably compliant on uneven roads, but firm up and respond well in corners. And the clunking on broken pavement is gone!
I'm disappointed the factory suspension wore out so quickly (just under 47k miles), but that seems to be the case on many cars.
