Well done, and congratulations Hyst!👍
I did both the 24h Le Mans races in the used Mazda 787B, without applying the chassis refresh. 48 hours of violent shaking whenever I went above 250 km/h, and spinning out every other time when applying the brakes made me hate that track with a passion.
So I recommend the Nürburgring 24h, you don't have to worry about the chassis wearing out there. I used the Mazda Ameyia Aspadradrink (or something similar..
) RX-7, for a very comfortable win. The track is so much fun, though the race probably won't be as close as the one you just finished.
Look around the board for suggestions on what car to choose, you'll want it to be reasonably close to help fight the boredom for 24 hours.
If you're looking for a shorter race, then El Capitan is a popular choice. Check out this
thread for a large number of possible cars for an entertaining race, look under endurance races: El Capitan in the first post.
