There is hard limit for 104 grid positions and 52 pitspots, that can be saved to AIW file, regardless of AIW "startinggrid" and "pitspots" settings. When I set "startinggrid" to 140 positions (that's what I want to set up), I can define in-game only 136 positions but again, only first 104 positions will be saved to AIW. As for pit spots - after setting "pitspots" parameter to 70, I can actually set those 70 pitspots on my track but still, only first 52 will be saved to AIW. Yes, I know right now there is in-game limit for 104 cars to set on track but with grid/pit spot positions is just about what is saved to AIW. I can define my target 140 garages/grid spots and 70 pitspots by hand but that will be unnecessary waste of time (we should be able to do this from AIW editor, regardless of in-game car limit at that time).
