This means that the further the car rolls and the left side extends - the lower the force will be on that side. The third point that is equally as important to this quick post is that the limit chain is not the only answer for you to get a faster and better handling race car.
We wish it were, but your overall vehicle set up and shock valving will still be the most important piece of the puzzle and when combined with a limit chain it can result in great improvements. Our Left Rear Speed Chain allows you to adjust something that traditionally is fixed amongst most all cars allowing you to fine tune your set up further than ever. We hope this helps and if you have any questions on your set up, our products, or anything stated in this post please feel free to contact us.

Generally, this adjustment causes corner entry handling to loosen and chassis roll to lessen. You can learn the "tuning range" for heights of your panhard bar by testing at the race track and taking good notes!
When adjusting for height, change both ends of the panhard bar. Otherwise you may introduce another handling effect by changing the angle of the panhard bar more later.
Also, if you adjust the height of the panhard bar just at the chassis, the rear roll center may move in the opposite direction. Angle During cornering the chassis exerts a side force on the rear axle and tires through the panhard bar. When the panhard bar is level, it transmits a wholly lateral force to the rear tires.
However, when the panhard bar is angled downward to the right, it transmits a partially downward force to the rear tires and rear traction is enhanced. Conversely, when the panhard bar is angled upward to the right, it transmits a partially upward force to the rear tires and rear traction is lessened.
The effect of an angled panhard bar on rear tire loadings is brief but very important handling. You can increase the panhard bar's effect on tire loadings by increasing the static upward or downward angle of the panhard bar. However, too much panhard bar angle can cause drastic changes in rear tire loadings during cornering and handling may become erratic as a result.
When making changes to the angle of your panhard bar, be aware of any effects to the height of the rear roll center. In order to determine the ultimate handling effects of the panhard bar's angle, one must consider where the panhard bar is attached to the rear axle--Read on! With this arrangement you can increase rear traction, hence tighten handling throughout the corner, by increasing the downward or decreasing the upward to the right angle of the panhard bar.
You can loosen handling throughout the corner by making adjustments opposite to those listed above. If the panhard bar is not attached to the rear axle near the center of the rear track, the panhard bar will load or unload the rear tires unevenly during cornering.
The closer a tire is to the panhard bar's axle mount the greater the tire is affected by the angle of the panhard bar. Conversely, a distant tire is affected less by the angle of the panhard bar.
By now you should have a good understanding of how some of the design elements and tuning adjustments of a panhard bar have a collective effect on handling.
If anything you have read is unclear, go back and reread the article before progressing. Tuning Tips. Height : Use chassis builders recommendation or start with the panhard mounted at the centerline of the axle. Asphalt - level. Conversely, a raised panhard bar which decreases chassis roll and normally loosens handling may actually tighten handling. FMI Knowledge Base. Search this site. A Glossary of Quarter Midget Terms.
