Based on the old times, THE one thing to watch out with Mission is the pivot ball screws that fix wheel hubs to the lower arms. They don't break very easily, but boy, did they like to bend, when you hit something
And when they bend, they can screw up the handling big time. It's a good habit to just turn them half a turn out/in between the races to see that they are still straight.
Maybe this has been fixed in the re-release cars, but I don't think so. The diameter of the detail is so small, that unless you make it out of some unobtainium, it will either bend OR break in a crash and bending is definitely the better option of those 2 (although much harder to troubleshoot after the crash).
Have a pair or 2 in your pit box and check them often.
