Wheel spacers cause increase in body roll?

I just received and installed a pair of Kics Project wheel spacers on the rear of my s14. (Rear only, no fronts) Took it for a test drive following and did some slalom at around 55-65 mph. Now prior to this, my car (which is lowered 2") has exhibited very little body roll during similar manuevers. But after installing the spacers, there is noticable body roll when slaloming at this speed. Does this make sense? The spacers are 25mm which is approximately 1".

You would think that the 2" wider base would give more stability in cornering due to lower effective center of gravity, or moving it more toward the center of the car. But perhaps, just perhaps, moving the rear wheels further from the rear shocks makes them less effective at dampening. Or maybe the difference in wheelbase from front to rear is a factor as well.

I know alot of people are running wheel spacers, so I am curious to see if others have noticed a similar effect, especially when running them in the rear only. It shouldn't be much different than running a lower offset, wider wheel; except that there is a little less tire width in contact with the road surface. Let me know what you think.

I guess there is a small chance that I am just imagining the difference, but I don't think so. I was pretty impressed before by the lack of roll, but now it is only average.
