At this point in the setup, moment center dynamics are of little or no use. The redistribution of weight that goes with the angled/left chassis-mounted bar negates any positive effects you could have achieved by dynamically balancing the chassis using moment center location as one of the tools to accomplish that.
For all asphalt applications and most dirt racing situations, a balanced setup using optimum MC locations makes the car faster and much more consistent. Around 90 percent of handling problems associated with stock cars are where the car is tight and will not turn well. The front MC location, as well as the balance of the setup you choose, are major contributors to this condition.
Differences in Handling Caused By MC Location
The primary reason two seemingly identical cars will handle differently can usually be traced to a front MC in a different location from car to car. It doesn't take much of a difference in arm lengths or chassis mounting point heights to cause a pair of cars to experience different handling characteristics. Just a few years ago, many professional stock car teams experimented with different upper control arm lengths to tune the handling while holding to preselected spring packages and weight distribution numbers. They were essentially moving the MC left and right in a trial and error way to try to find the ultimate handling balance for a particular race track.
Today, we know better than to waste time doing that. There is a combination of spring rates, moment centers, and weight distribution for each car at each race track that will make the car balanced and consistent. Knowing the role of the MCs and being willing to make changes so that the MCs are in the right position is one of the most important steps to take to achieve the total handling package.
