close to spinning out one time in 4 events. Granted, I am still a pretty timid auto-xer since this is my first year doing it (and since I just bought my Z in March), but they feel so much stickier than my street tires (245/35/18F 285/3518R Proxes T-1S). Even though I am a noob, my last time out I was only .8 seconds behind the class leader in SM2 here. He will be mine this Sunday!
