In terms of distance Gothenburg is similar to Stockholm ARN indeed. Also check Stockholm Bromma, it's a little closer, small airport, easy to arrive and leave. I flew to Bromma 3 times. Also checking Stockholm Nykoping (lots of flights with Ryanair) can be interesting. This year we're flying to Oslo Gardermoen, which is the closest to the rally now. Before booking it's interesting not only to compare the costs of the flights themselves, but also check the price of the rental cars. I don't know why, but the prices of rental cars can differ a lot from time to time and from airport to airport.
It looks like it doesn't. At least it's not in the list on FIA website: https://www.fia.com/file/65105/downl...token=P01P9A00 (only Evo X inside).
EDIT (after private chat with PLuto): It's still permited in FIA events under exception.
I know that this year is last one for IX evo's at FIA championships
