It's totally cool. TC1000 is my main track in real sports driving life. If you wanted the details for improvement. I can take the pictures at TC1000 and share with you.
Superb job! Such a high quality little track. Very fun to just throw some cars on it and have some good moments. Just had tons of fun with jandrovi's tuned physics E46 M3 on this track: https://youtu.be/O892fCkluIY
