REAR END SETTINGS
square the rear end
The pinion angle should be 3 – 5 degrees down at the front. The starting point for the panard mount is 4 – 8 degrees up on the frame side (about 5” from the top of the frame to the bottom of the slider). The rear mount should remain close to the center. REMEMBER to free up the car with the panard bar you must lower the slider on the frame side. To tighten the car up you must raise the slider on the frame side. We recommend that you only move the slider a ¼” at a time. Right rear radius rod should be level with driver in the car. Left rear radius rod should be up in the front 10 degrees. Raise left rear for more forward bite on turn exit.
