Corteco M3 engine mounts are always my go to
Please confirm the P/N for Engine Mounts is 22116779970 and the Flex Coupling for Steering is 32301094703.
BMW Genuine Part items. If anything better and not stiff.....Corteco sounds good per reviews.
Any good on Lemforder?
Would the Transmission Mounts also a requirement to be replaced? Or this is a Preventive Maintenance?
What type of Steering Fluids for the ZHP?
I verified your part numbers for engine mounts and steering coupler are correct. My mechanic recommends Corteco engine mounts as well, I think that’s what he installed on my car.
My ZHP has 152k miles and needs new differential bushings. I have a clunking noise, I think that’s the reason.
Not sure about your other questions, let’s see if some else can chime in.
Genuine for steering coupler
I like UUC black trans mounts. For OE go lemforder. M3 version is double cost and feels the same but likely will last a little longer. I typically like Corteco or Febi (Bilstein) for rubber mounts and Lenforder when a bearing/ball joint is involved.
Dexron III ATF for steering fluid. This is what I prefer:

At least need 2. But I didn’t check on my rack swap
Corteco or Lemforder brand engine mounts are both good options. I prefer the E46 M3 ones over the non-m parts since they are full rubber vs being fluid filled. Consider them an oe+ upgrade for non-m cars. Last time I ordered a set cost was roughly the same.

E46 M3 mounts are also fluid filled. Only the Group N mounts are solid rubber.
