Bimmerworld sway bar endlink failure

I bought a pair of these last year from BW. I've put about 4k miles on the car with 1 track day, and in the middle of installing my Hotchkis bar today, I noticed the stud portion of one of the heim joints rotates within the inner portion of the joint. There's a fair bit of play which I'm sure will get worse with time. Has anyone had these fail in a similar fashion?



Also noticed that the nuts included with these endlinks are soft as butter and strip extremely easily...
