Can anyone please advise me on how to tune the Audi R8 Race Car for the LeSarthe 1 track? I need to use it for a 24 hour endurance race, but we can't have any driver aids at all. I'm struggling without driver aids. How do I tune it to the best of its ability? I would also like to minimize tyre wear. If possible, only changing every 6 to 7 laps? Anyone? Please?
