--Yeah, that would be Bill's car, very impressive. Some interesting
innovations on the front end as well. I don't have pics, but the best I've
seen was Baucom's car, particularly the front suspension.

Jim,

Nice work!

However, I do not think this has an effect on roll center.

I believe with a panhard rod the roll center is where the rod crosses the
left/right centerline of the axle.

--Csaba, good point. I think you are absolutely correct about the panhard
bar. To affect roll center, one of the additional modifications noted above
would be needed. In the meantime, I'm hoping, at minimum, this new setup will
be more secure. :(
