[E55 THIS]

then I came across this article http://dinancars.com/whitepapersFile.asp?ID=5
I know he mentions the e36 briefly, but maybe someone from evo, rogue, or another member could comment. Would this apply to the M5?

E55, I had pulley on my e36 m3 S/C and then turbo with a aluminum flywheel and never had any issues at all. Since I had a lighter flywheel the pulley kit didn't have a crank pulley, you couldn't do both or you would be likely to have damage like he explained with crank tortional stuff.
Both kits e36 and now on the m5 are Evosport.
I think they just had a price reduction, if interested you might give them a look.

No one knows anything about this concerning the e39 M5?

E55: Our kit does not replace factory damper.

On E39 M5 it is a separate piece, unlike most other cars where it is incorporated inro front crank pulley.
