Thread: Panhard bar opinions

Tweet

Mike had some really good points about the geometry in his post, and it prompted me to try to find what I remembered to be a very concise explanation on YouTube. I had forgotten about the "pre-load" step to minimize, and almost eliminate side play by calculating (or measuring) the "Sagitta" and setting your differential offset from center by 1/2 of the Sagitta value. Then as the suspension travels the side to side movement is 1/2 of the total, likely barely noticeable! Here's a link to a really good explanation - https://www.youtube.com/watch?reload=9&v=liR1--EHMg8

Thanks for the link Roger, a good refresher on geometry is always helpful. Once I get back working on the car I'm still hoping to find or make room for a Watts linkage, but if not I do have references for a proper Panhard bar install!
