Solved!
I downloaded this mod, just released today, from Race Department:
https://www.racedepartment.com/downloads/alfa-75-gt-legends.23608/
1. The shadows work properly, even at Donington
2. When driven by the AI, the Alfas perform at accurate level, not 3-5 seconds faster than the BMWs and RS500s. The Alfas were off the pace the whole series.
3. The skins are accurate for the various competitions these cars raced in circa 1987, unlike the other mod
4. The stance and ground clearance of the car is more accurate.
Great mod!
Just need the Holden Commodore V8 and my field for WTCC87 will be complete!
