Yes, I thought so, just hadn't posted yet.  The wider track increases 
"tramlining", or the tendency of the car to follow road irregularities.

On my 90Q I have 15" speedlines, et38, I believe, in place of the et45 
stock bbs's, and it is twitchier (not as eager to go straight) and wants 
to steer "down" road camber.

It is also a bit "scrubby" on tight slow turning (full lock, pretty 
much), which might be the offset, or perhaps running 205 vs. 195 tires 
(I doubt it), or perhaps a gruntly torsen arguing with the road.
