Just came upon this thread. I have a good number of track day pics. This is one of my favorites from BMWCCA Oktoberfest back in '09 at Road Atlanta.
That trip was very special because it involved a two week road trip with my dad all the way from Mexico City to Atlanta and back. I reconnected with my old man on that trip and had a blast. I no longer have the E90. It was a lot of fun.
