Wouldn't it be worth a shot to launch a series with GT3 cars only? ( urd mod to take the safe route ) Multi-class racing is cool, and the real enduro spirit, but on the other hand, 30 to 40 cars in the same class on track is epic as well!
Especially now the new Nordsleife is launched, all tracks to sort of take over the real life schedule is available.
I could start dreaming with a 24h spa / nordsleife in 1 season.....
In the background I am having some ideas for a close race 60min sprint GT series with driver rankings, but early days. First of we have this:A series like the Blancpain would be nice. 60 minute race with 2 drivers per team. 6 races in the season and one of them a 6h or 1000km race.
