LOL. Hell, after watching that video and ALL of the precautions, notations and recommendations, makes even MORE sense to just buy a winter beater and drive the GT-350 in weather it prefers. JMO.
I had a guy tell me he dd his on the east coast. I am from nj and I dd mine. They said 275/40/19 for front and 285/40/19 passing along. I havent done it yet as the winter has been great in nj
