If there's an endurance feature that we could have, please could it be brake swapping. Apparently brakes can be changed with a driver swap but only after they are destroyed which isn't ideal. Please add as a pit menu option. One thing to note, we had an event where a guy lost both brakes one after another, got them replaced with a driver swap, and then lost the engine. The sim classified the DNF as a brake failure even though the engine exploded.
Driver changes tend to reset many items. I suspect the lack of a replace feature caused the game to simply choose the first failure in the log. Brakeshoe replacement is another 'thing' that didn't get forwarded from rF1/GTR2.
As far as I’m aware from the HDV files, different brake compounds are still not supported either (although you can fiddle this with Upgrade files…)
