I have a track day in 3 days and probably should figure this out ASAP.
If you can fix it in time, I would. Unfortunately, I'm not sure if the "jiggle" is normal. But you're risking the cost of the HPDE cost if you don't fix it... Do it once with genuine BMW parts and it'll probably be good for the rest of the life of the car.
