Hi, guys,
here's a video (full video coming soon; will post it here later) of my crash. Luckily, I was smart enough to buy a car with a roll cage, bucket seats and 5 point seat belts for track days... Drivers bucket seat was too small for me, so I bought a new one (just before this track day).
Nemunas ring track (Lithuania) is one of the most dangerous tracks in Europe and does not forgive mistakes... Mistakes usually result in a totaled car. Almost my case.
I'm glad I did not track my 335i. The outcome would have been much worse, both - cost and safety/injuries wise.
Drive safely.
