Since this gentleman asked for personal experience, I must assume that you have installed and used urethane upper control (thrust) arm bushings and had squeeking problems.
Did you use the silicon grease that came with the bushings?
I have installed several sets on customers' cars and not had a single complaint of squeeking from any of them has arrisen. I modified the thrust arms on my personal 535is with grease fittings "just in case," but have yet to hear a squeek.
Please share with us the supplier of your components so others can avoid your problems.
The ones I've used are RTRS and BMP supplied.
BTW, no increase in ride harshness and the steering "turn-in" is crisper as well.
