I've got Hankook RS3 at the moment in 255/35/18,
Heaps of grip, possibly more than the R888 from other people's reviews but I haven't had a chance to give them a good squirt yet...
But the best part is the road manners are at a really acceptable level. R888s make a shedload of noise, but the Hankooks are relatively quiet, even if they do make a bit more noise than a Michelin, it's a totally acceptable level and a very minor trade off for awesome levels of grip.
I bought local as well @ Jax Haberfield
