I had on my Mk3 the cheap Ebay Hottuning coilovers lowered to the floor on 17inch rims. I found this very hard.
I then had Weitec coilovers on the same car, same height and wheels. This was still hard but very forgiving and a lot softer compared.
Obviously with both of these set ups they were so low that it was always going to be hard.
My brother has just got some FK coilovers, not sure on the model but not the base spec, these are VERY comfortable and that car is on the floor also.
Overall i would say, providing your not lowering to the floor, a reasonable set of FK or Weitec would be fine.
