There is a bug in BTB Evo where the pace car location is not stored properly. I could bet that the pace car appears in the origin, coordinates 0,0,0 ... That's why i start with 0,0,0 being located in the pits (or under it....). I haven't studied this further but it was something to do with the last pitbox location being the pace-car coordinates but i might mix up that info with rF generated AIW..
And i have to comment on the GTR2 vs Race07: GTR2 has more variety regarding ontrack conditions. But and it's a big but, FFB is awful and the game has inbuilt inaccuracies to "help" the driver. For me GTR2 feels like driving with a car made of rubber where as Race07 feels like precision.
