Ditto on the Toyo T1R's, I'm also using 255/40 R17 on my GTR, indeed they do seem to exagerate the HICAS but it's not too annoying, infact it's sometimes quite good to actually feel it rather than thinking the rear end of the car is just possesed. Dry performance is very good, i think if the car is putting out more than 450bhp though it's hard to find anything beyond having pre-warmed slicks on that won't spin up when you plant the loud pedal......especially on the NZ crappy roads!! Wet perfomance is pretty predictable (read good), no nasty moments so far, got all four fitted/aligned for NZD1000 so isn't bad for a performance tyre.
