Hello.
Feel free to move to correct section if I'm in the wrong one.

The car in question BMW e90 320D with swapped M57 from 330D. Basically it's 330D, apart from the original chassis.

So. I have a ton of vibrations between 60-80mph, when I'm acceleration, I'm fully aware I need to change the engine mounts as they're dying, gearbox mount, just in case, but that's not the main issue I'm having.

The problem is that I have OEM 26117546425 front coupler / guibo / flexdisk (whatever you call them ) on the front at the moment. It's superseded by OEM 26117610061, which would be fine by me. Both of them fit as far as I understand. Now, when I check the RealOEM by putting 330D, not looking by part numbers, I get another OEM part number for the front, this time it's 26117542238, so the confusion starts to get messy in my head.
I found two`s from FEBI Bilstein one is diameter of 140mm, the other one is 152. Both of them are 7610061`s. Correct me if I'm wrong, but the bigger aluminum 152 won't fit, am I correct? The normal size should be 140m in diameter. Is there an upgrade available for them or is the OEMs good enough.

Same thing for the rear one.
The one on the car is 2611 7542238. RealOEM says - 26117518443 should be there, BUT Superseded by: 26117546426 (02/25/2005 — ), nonexchangeable retrospectively. Which one should I look for?
