The reduction of a few mm of rake (offset) will have a very small % effect on wheelbase, but a relatively much larger % effect on the trail.

As always, a smooth and free-turning headset is most crucial to hands-off riding. Many headsets are carefully adjusted with front wheel and bars removed, yet the mechanic doesn't secure a quill in the steerer when performing the adjustment. Result is often binding and quickly brinnelled headset races. Ouch.
