M5 solid metal trailing arm bushes on a 535i

[BigKriss]

I was talking to Anthony (M5 in Calgary) and he was saying that the M5 uses "solid metal trailing arm bushings instead of rubber ones - I wonder if they'd fit 535 trailing arms..."

I know the trailing arms are different, ETK gives different part numbers, but can I put the m5 ones on my car. Here are the differnet versions.

See part 2 here:

The 535 uses rubber bushings:

or are the Kmac adjustable ones better again? (http://www.k-mac.com/imwinds/asmbly.htm) The Kmac ones fit all e34's including the M5. Looking at the point of view that price does not matter. I want performance (still pondering more upgrades).

A big thanks to Anthony for the information.
