I just worry about the issue pulling the bolts out of the body or possibly damaging/cracking the mounting points like an E46 M3.
That's a common thing to have the rear sub bush evaporate, had the same issue went through with it while I was in there did every suspension component on the vehicle as there's like 80 bushings in these cars and they all wear out when the 100th owner dumps the non-maintained vehicle onto the next guy. All my bushings were completely broken and so slam on a good start.
The bentley E53 manual says you need to completely drop the subframe out but there's a special tool I used that lets you remove and install the bushings just with a floor jack and one bolt removed, this saved me a lot of time and patience. I also heated the exhaust hangars with torch to bent it out of the way and then back again for access to the rear subframe bolts.
