Mike,

I believe the "other gentelman" Dave was referring to is Monte, and that he (Monte) is correct that the IC is NOT changed by the Cal-Trac's. But by changing the bar position at the front you can change the amount of downward force applied to the rear end.

While this goes against what I have come to understand I will accept the word of these two experts (at least until I can find a way to prove otherwise of course!)
