Gary - Actually, Anti-dive for the front suspension is if you have the opposite of kickup in the front arms. When you use the new GP low roll center blocks, they are actually the height of mid rollcenter. So for example if you use the new low roll center block up front, and the 0F pivot support, your arms will be tilted down instead of kicked up.
And I'll add another thing about the steering bell cranks. As TSR6 said, there are two sets of holes to put the belcranks in on the new chassis. "Flipped" actually means that they have taken the belcranks, and flipped them upside down and turned them around 180 degrees so that the shorter arms now face forward.
