Well, I go to BimmerWerksShop in Beltsville MD. Amr will use your parts if you want him too, but if you get a funky result, you will be paying him to do it over with factory parts.
My experience was that way with some transmission mounts. I had the 'un-named' after market 'with limiter cups' .. Totally caused crazy vibration. He had some spare factory mounts [new] - put them in and vibration went away. Mind you this was during a driveshaft replacement. My rear ujoint had frozen [and I was getting clutch done at the same time] so my 'genuis' thought 'get these 'upgrade mounts'' put in. Ya that was a bad idea.
I just had some coilovers installed there, and got an alignment with that [part of the job].. UNfortunately they do not do corner balancing so ...
