A difficult question.
I happen to have a set of these ->

These are the bushes from the M3 E46 GTR.
I am not sure what arm the GTR has.
It's not obvious to me how you can use them

Does anyone have any info about the M3 GTR rear arms ?
Mr Gorilla maybe ?
I am considering to drive to Munich to crawl under the M3 GTR to see what the feck is going on with it's suspension.

I am sure they will think I am strange
