I just got back from two days of track with my e92 M3. The course was relatively fast, in the back straight you reached top speed of 140mls/h, after which you had a bus stop at 60 mls/h. The brakes didn't last. I experienced brake fade by the end of the first session. And by the 6th session, the brakes warped. So before you go on the track, look into getting different pads, or even upgrade to a set of dinan brakes and that will not void your warranty. However, dinan doesn't have brakes for the m3 yet, but ask if the brakes ment for the 335i fit. As far as the suspension, if you're a novice you dont necessarily need any adjustments just yet, the car handles amazing.
