Sorry I didn't reply sooner. I stopped visiting the site for the most part, there is only value here if you're looking for something specific.
I live in Texas and even though we had ice this year and a little snow, I left the Camaro in the garage. I will say that dumping the P-Zero's was the greatest improvement in driving pleasure I've made to the car. With the all season Goodyears I suffer no noticeable drop off in traction when the temp goes below 40. Hope this helps and wasn't too late.
