bspec, ARP was very dismissive when I called them last month, blaming the nuts, but since then, and especially after this video I think that they realized they had a real problem and they sent me replacement items.
I was annoyed at first that they were blaming me for not mounting the stud properly. I actually had given up and bought short nuts instead.
Now I am receiving the new parts, I'll have to reinstall one set of studs, lucky this time around they are front one.
So for me I received 2 bad set of studs out of 5 ordered, all on amazon.com
