I haven't raced yet, but am planning on it. I only have a little over 600 miles on it, so haven't wanted to abuse it too early, but it's pretty much broken in now. From what I have been hearing, they don't REALLY run well until a couple thousand miles.
I am planning on heading out to National Trails soon, probably in the next couple of weeks just to get a base of what this monster can do! I'll drop a line here to see if you guys are going so we can try to meet up.
I am also planning on running some Autocross with the local SCCA. Going fast in a straight line is fun, but so is turning!
