Miki,

I noticed the same thing on my '96 328is/sport when it was stock.  I think
it's a combination of tires and the suspension geometry.  My stock tires
were Pirellis P6000's (225/60 ZR16) and when I switched to Dunlops D40M2's I
noticed a small improvement.  Shortly after that I've upgraded to M3
wheels/tires (Michelin Pilots MXX2) and witnessed another small improvement.
But the biggest improvement was when I swapped out my sport suspension for
M3 suspension.  The big difference is the way the front sway bar attaches to
the strut instead of the lower control arm.

Hope this helps...
