krzyss, Nice post. Interesting story, I have both the Hankook evo 12's and the Sumitomo HTRZIII's, in the same size (two different sets of tyres of course) - the ZIII's are much wider.
The Evo12's have decent grip, but they really have a "squishy"/soft feel to them. The ZIII"s have much better feedback w/o being as harsh as StarSpecs/Neovas, similar traction "feel" to the Evo 12, but feel slightly sportier overall. I'd faster recommend the ZIII as a budget alternative than the Evo 12 K110's (well, aside from the 595 RS-R)....cuz they are priced about the same IIRC, and give more value for money IMHO
