Thanks for the input Jay!

Looking at them now, 280 TRDWR and on sale at tirerack.com for $185. Definitely a good option!

About riding on a stiff sidewall..I'm actually trying to stay away from brands like Falken for the reason that I want the 255/35/18's to have SOME flex in them. Hence I'm more interested in a softer sidewall to promote less understeer. Which brings me to look at brands like Hankook, Dunlop and maybe Nitto if I could get more concrete feedback. I didn't know the S04 had stiff sidewalls. Which I am assuming you're running a 225 or 235 and 40 or 45 A/R on 17's. I think I remember you telling me but that was long ago.
