I ran the Ventus RS2 Z212’s on my GTO this year and wasn’t all that impressed. It’s hard to do a direct comparision between them and the Azenis 615’s though since I had the Azenis on the Fiero. It seemed to push forever coming out of grand bend at Dunnville. Some of that I’m sure was due to the stock alignment and suspension on the GTO, but reading the Grassroots review makes me think some of it was the tire.
As for wear, 3 autocrosses, one track day, and a summer of hooligan like driving were all they were good for.
