The reason for the excessive lift on the left rear is from the bar angles, most notably the top bar. The reason the lr moves so far forward is from using very short length bars. The lr spring is typically mounted on the back of the birdcage so the spring will compress as the b/c indexes.

If you want to shorten the bars you need to keep them both close to the same proportions that they are now. Changing the length of just one bar will change how the b/c indexes and also has a significant effect on i/c movement. A 1/4" change in the length of one bar can make a dramatic difference in handling on a 4-bar.

So what are most of todays modifieds that are running 4bar left rears typically running for bar length. How about the lenghts of the right side if you are running a zlink. Are they running both bars the same lenth or the front bar shorter. Thanks
