I just read the article in the Motortrend magazine that talked about the new M5 rear diff. Here is the part that caught my attention:
"In the case of the differential, it's mounted solidly-aluminum to steel, with shear panels to further stiffen it. This is similar to what is done in the M3 GTS.
I couldn't find pictures or information on the diff of M3 GTS. Anyone know if the M3 GTS diff has re-enforcement or it's exactly the same as the regular M3?
I'm glad you posted this.
Putting the solid rear bushings will prevent damaging of the subframe and reduce if not eliminate all system compliance.
It is a counter intuitive change as many always believe that a solid mounted rear end will destroy the subframe and unibody mounts. But if done correctly, it will further improve it hence the reason the GTS and new M5 have it.
