FYI - On my E46 I had Potenza RE050As on the front and Potenza S001 on the rear for some time and I could notice the difference quite a lot. It is not a case of bad handling though, no extra understeer, it was more the fact the car was more twitchy and skittish over bumps.
BMW told me the E46 was very susceptible to this issue, but I don't know about the E39.
If the E46 is the extreme I would say it is bearable, so if the E39 is only affected by a minimal amount then you should be able to live with it with no problems.
Is there no E39 forums you could ask about to get a more informed opinion?
