I've used Delphi control arms from Rock Auto on my 2014 335i. They were garbage because they clunked within 5000 miles from the install. I switched back to genuine BMW control arms since then and I've had no issues.
I understand. So am I, but I had this issue and when I went to retorque the nut for the rear bushing on the front control arms, I noticed that it was a bit below the torque spec. It wasn't much, but it did resolve some slight clunking that I had.
