We put some old 225/50-15's from our Volvo 240's on it for the Novice day. They are 4 years old... lol.
We are limited to a 15x7 wheel, so 245 may be the limit.
I doubt we will be able to get to minimum weight.
I doubt it will be challenging for wins in ITS. The 240Z's have quite a bit of time on us. We'll see how it goes. We are hopeful, but also realistic.
