The highway entrance ramp when I leave work has a slight curve and is about 1/2 mile long. When I'm getting up to speed and shift from 2nd to 3rd my M3 gives me a big swaying motion mostly in the back end as 3rd engages. The tires never actually slip but the car sways heavily. I would swear that the power is engaging unevenly or the suspension is 'relaxing' right when 3rd engages but this doesn't make a lot of sense to me. The swaying cooresponds to the amount of power but is obvious even when I shift out of 2nd at 3500 rpm, so fairly low levels.

Other than this my car stays hooked up nicely in corners. I have my SMGII set on the 5th setting (one down from the fastest clutch setting).

Thanks for any ideas or suggestions on how to fix this or if I just expect too much...

My limited experience with E46 M3's says that they are something of a "tail wagger" and would benefit from stiffer sways & springs. I can't say that I've experienced exactly what you've described, but I have felt similar motions from the car when lifting or transitioning from braking at turn-in.

That said, it would be best to have the car checked out for suspension faults.
