Late this summer when it was warm and after they had a few hundred miles on them they would hold pretty much full throttle 2nd gear pulls (~450+ rwhp from others with similar mods). Maybe a hair of spin right near redline, hard to tell since you go through the gear so fast. They are good in the rain on the highway also, although I haven't tried intentionally romping them in the wet obviously. I have them in 255/40-18 all around on my Jag XJR, and they are fantastic there also. One caveat; they do lose quite a bit of traction when the temperature drops. If it's a damp morning in the low 40's you better watch your driving and power inputs.
