A friend of mine autocrossed his Celica on them. I was quizzing him at lunch the other day and he said they stuck really well and were quiet on the road. After looking at our options, I think I'm about to order a set myself. I've had the Michelins only because they came on the redpra when I bought it and they were very good, but considering the price, I can't imagine they'd be TWICE as good as the Sumos or Falkens. I sure miss my old Yoko 509s tho.
