Personally I would extend the straight after the pit lane (assuming a counter-clockwise race direction) so you can maybe swap the 45° R1s for R2s or a combo R2 and then R1..---
You have R3s right before the main straight so there should be space.
Huh, I never thought about that. But then, where to does the grandstand go?
Yeh, I might look at that. The beauty of the software is that it helps with angles and getting everything aligned and matched. It took weeks and lots of discussions to get just that layout. But thank you for the suggestion. I will look at that later. Gotta get A track going first.
