First set were really bad. Honesty, I didn’t like shipping them back because I felt like they’ll just be put back into stock and shipped again.The set I returned was assembled incorrectly from the factory then corrected. The issue is 6061 aluminum is still real soft regardless of the quality. So the incorrect assembled left damage on the both mountings surfaces. That being said the second set is good to go and came in about three days. Right after I sent the bad ones off. The studs are not as good as stock wheel studs but fair at this price point. I’ll be inspecting them every rotation about 5k
