i'm not tracking the car, so i cannot speak for that.

however, the theory of increased handling due to increased track is sound, otherwise the guys on this forum that are tracking their cars wouldn't bother with super aggressive offsets.

i certainly don't see how increased track in the rear of the car could be detrimental. the rear wheels are not pivoting like the front, so only verticle movement is considered. as long as the toe angles are proper for the width and offset of the wheel, increased track should theoretically always be better.

the front is a bit different. by changing the offset (and probably the track), the scrub radius that was originally defined by the engineers is changed, hence my afore mentioned issues with bumpsteer and tramlining. increasing track is good for grip; however, a change in scrub radius is bad for steering feedback and may also contribute to understeer or oversteer.

racers chime in, and let me know if i'm way off base.
