These guys sell everything you will need:

Which is where mine are from . The reason I chose these as they are designed to avoid the bump steer that other types create by positioning the beam at the correct height.

Also, as above - no more NVH than standard.

I discussed this in depth with Obioban (Ian off the M3 Forum) as he has fitted every single different iteration of suspension component to his M3 over the years, so because of him, I knew in advance what would make a noise and what wouldn't. So just avoid up-rated engine and gearbox mounts and diff bushes and all will be golden

Now iv got this in my head. I’ll have to try it ,, as I’ve already got it all set up in a spare rear subframe, solid akg bushes. Some vac spherical top inner arm bushes set up , and two spare rear trailing arms with all new wheel bearings and new bushes with new front spherical bearings , now just have to wait for a dry day ,

I dispensed with paying for the solid subframe bushes and simply welded the subframe to the chassis... no difference in NVH

That might make servicing the car a bit harder

why? nothings's affected. prolly a tad bit harsher/ stiffer on the road.
