Dropping the center wheels further will help greatly, if that is the problem. Of course, too much drop and you'll have a bot that rocks back and forth.

One thing the Jaguar FAQ mentioned is a too-tight chain. I remember working pretty hard to get those chains on. How much of a factor might that be?

If the chain is so tight that it doesn't budge at all when you try to wiggle it, it is too tight. Tight chains add friction.
