I've got Bridgestone SO-3's and I have to say that there the best handling tyre I've ever driven on. Standard issue on HSV, porsche and most HWP cars are suited up with them. I've driven on yokohama, goodyear, Marshalls(very bad), Michelins and SO3's better them all in the wet and dry. I get around 25k out of a set. Price is around $370ea
