Although I'm not there yet I was thinking about possibly going with koni Special active dampers when the time comes. They seem to be quite well regarded. My only issue is that it would potentially classed as a mod on insurance as it's not OE spec.
Back when I modded my 2003 Ibiza sport 130 I'd got a weitec suspension kit which KW owned and have now rebranded as ST suspension. It was great, everything about it was better. Original suspension was really crashy. The weitec was a smoother ride and had less roll with about 30mm drop. Strangely felt a lot more like my brother's cupra of similar age. Not sure why the sport suspension was a worse ride than the cupra.
