Falcon XY GTHO Group Nc race car, rear suspension lateral movement. Does it need a panhard
I wanted to prove if with a leaf spring setup on my race car I needed a panhard bar or watts linkage for lateral diff housing location, so I put a camera under the car to prove it. The springs have polyurethane bushes and the diff housing is mounted directly to the spring without the original style sandwich rubbers. If you look at the top LH corner you can see the sway bar mount which indicates lateral (sideways) diff housing movement if compared to the edge it the video frame. The answer looks like you don't need lateral location. However if you want to control rear roll center, then either of these lateral location devices are well worth the trouble to fit.
