I have dialed out the under steer almost completely and found her to be very neutral, with just a hint of over steer when I mash the loud pedal at the right time. The brakes are one of my next things to look at as the stopping power just wasn't where it needs to be, and I scrubbed time in the slower elements in the course.
I also dB'd at 72, and feel that I shouldn't go over the max allowable of 94 if I delete the mufflers from the car. It should free up an additional 35'ish pounds from under the bumper.
This weekend is another event but it will be the tight technical course due to the location.
Learning to back end the cones is coming along too.

Sounds like you've got the set up just about right for autoX! Ideally you'd like just a bit of off throttle over steer, but not so much that you can't regain traction by getting back on the gas. I deleted the muffler on my 3.0si and it registers about 90dB max at the 50 foot distance they typically monitor at so I'd expect you'll be good for the 94 limit. Your M should have more than enough braking power for autocross with the stock system, what pads are you running?
