I love my V12's. One day when I make enough money, I will buy the PSS's. I'm SURE these are way better, but honestly the Hankook's kicks ass for what they are.
Hankooks, Conti's and PSS's seem to be the tires of choice around here.
On my RX-8, I rode Falken FK452s. $10 more a tire I think, but they don't last as long. Stiffer walls however.
