Something is wrong with the 1977 crew mod. Can't download part2. Can you fix it?
I was struggling to get the Shadow to keep pace with McLaren, Ferrari, Lotus... so I I made Shadow a customer car of Ferrari.. (Season Data>Vehicles>Ferrari and copy "1977_Ferrari_engine file. Then go to the Shadow folder and paste it there. Change the name to 1977_Cosworth03_engine) Your Shadow will now have the horsepower of the V12 Ferrari. I guess you could do this with any combo.
