Check out vw vortex, it's us based but Infos stil relevant.
Personally thou I'd up the budget if you could. I went in a friends mk2 golf with jom coilies on and it rode like shit. Was still at a sensible height too which was suprising. I fitted FK highsports to my passat and love them. Adjusting collars out of the back, helper spring out the front it still rides nice, handles well-ish (as well as an estate should). I went to adjust them the other day and they were still easy to adjust, my friends jom setup was solid even with copper slip on.
Don't get me wrong, the joms seem consistent and reliable, they've been on over 18 months now trouble free but I wouldn't like to think I've got them everyday.
