That's right Pat however it seem s to be very unobtrusive, I've never felt it cut in.
My latest 166 also seems to pitch/dive/roll a lot less than my previous 2.
Just some advice re wheel size. I've now driven 166s extensively on 16s, 17s and 18s. I have to say that the 18s were terrible - the torque steer was excessive, it tramlined, the ride was awful - looking back I don't know how I coped. The 16s are obviously the best for ride but their does seem to be some side wall flex and turn in isn't very crisp.
Overall I'd say 17s are the best compromise. Handling and Grip are superb with only a slight inclination to tramline and the ride only suffers slightly.
