A frame side Panhard/J-Bar mount that adjusts quickly can maximize practice time ensuring you have every chance to dial in the car. The slider version allows for precision locating and increments as small or as large as you need.
Even so, there is still more to it. The goal is to get the most out of everything. Maximum down force in combination with soft tires creates an opportunity. Of course, you may have a sway bar in the car the diameter of a sewer pipe so how do we balance the Panhard/J-Bar in association with a ton of rebound in the front shocks and a sway bar that locks down the nose? Again, there is not an answer as all of the variables have to come together to create the right feel for the driver.
A J-Bar bracket with a slotted adjustment allows for quick changes. A wide adjustment range with slots verses holes will help your car to find every ounce of speed.
Raise the Panhard/J-Bar when:
There is a ton of grip available.
When you have high amounts of down force.
You have high banking and smooth transitions.
When the car is solid and easy to drive deep into the corner.
When the driver can pull down a groove at will.
Lower the Panhard/J-Bar when:
The driver doesnt like the corner entry feel.
The car wont stay on the bottom.
The track is bumpy or has little grip.
When the car feels fast for 2 laps then drops off considerably.
When left side tire temps are low.
Think opposite when:
1. The driver says the car is tight yet you have thrown many adjustments at the car that should have made a noticeable difference none of those adjustments are working. This may be a time when a lower Panhard/J-Bar can add more positive rear steer through added roll helping it to turn in the center. A gain in side bite would be the goal increasing overall grip giving you new chassis adjustment options created by this new baseline.
2. The car needs more side bite so the driver is timid with the steering wheel on corner entry so he misses the apex making him believe the car is tight. Pay special attention if the driver complains that the car snaps loose after being tight in the center as this can be an indication that lower is better.
3. When you keep raising the bar to help the car turn and there is little change.
4. Panhard/J-Bars are so easy to move that sometimes it pays to simply raise and lower it a small amount and just use the trial and error method.
