Great meeting you out at the track. Hopefully it works out without being too costly. Although huge clouds of blue smoke were rolling out of the back when I saw it during your first session while I was taking pics up by the balcony.

To be clear - this is not an M3 engine problem. I witnessed M3's running flawlessly at the track all day!
