Curt,
You'll have to bear with me on the suspension info. Since I didn't build the car, I don't know every nut and bolt on it (I wish I had enough skills to do it myself). The front suspension is the standard FFR kit suspension, which I believe is unequal length upper and lower A-arms (I know for sure about the lower one, I've cleaned it once or twice). I should probably snap a picture of it for a better description.
I'm running 17" wheels, with Firestone Firehawk SZ EPs, size 245/45 up front, 275/40 on the rear.
By loose, I mean oversteer. I have another autocross on Sunday, so I'll get more feedback then. But in my first event with it, on every run, the car turned in quickly. But once I was about at the apex of the turn, the back end would start to slide. I had to drive with an eggshell under my foot when getting into the gas coming out of the corner. The back felt pretty twitchy. I had to catch it several times, and nearly went all the way around once. It's fun to drift the car like that

, but it's not the fastest way around the course, which is what I want.
