  1. Couple of comments. String the chassis to find the centerline & measure 4 link chassis bracket locations to ensure they are exact side to side & front to back FIRST. If not, everything measured from there on will be off & you will have to start over.
    Using the string method eliminates measuring from ball joints (or other components) as well as if the car has staggered front wheelbase. Another reason for establishing centerline is getting wheelie bars square to the centerline. When there's rear steer the wheelie bars should be adjusted to the centerline.
    Another method of measuring pinion angle is to remove the driveshaft from the equation. Measure rear end housing angle & Engine/Trans angle then calculate from there.

    Great videos, thank you for sharing!

  2. Good video.
    When you say that you can't use the 4 link to preload in a stock suspension car…do you feel this holds true even when you add a wishbone?
    In my experience, even a triangulated setup will be able to use the upper bars to preload IF you have added a wishbone to the "stock suspension" mustang or G body
    Thanks

  3. You couldn't have nailed a better explanation better. As a guy who knows nothing about how to setup a 4 link I now feel like if I had one I could adjust it with some confidence.
