Joe, you can run anything. They are just requesting that there are no studded tires. There is just running against the clock, so its not really a competition.
There might be a 2wd and AWD as far as classes, but then again they might now. I wouldn’t expect nothing crazy its just for a good time. I’m taking my RSX, though I’ll probably dump it after a few runs and switch to my friends S2000. At least they both have snow tires so I have that going for me lol.
I really don’t intend to take this too seriously and worry about times. Thus, my ESP will be turned off and I might even run some all-season tires vs. snow tires. The snows might provide too much grip.
A few pictures if anyone wants to check them out. Event was pretty fun. Event had a few snags and was cold as hell. But worth it to go balls out through the snow. http://www.autoxphotos.com/gallery.asp?categoryid=453
