Don't understand why the long bar made more side bite for you. The shorter j-bar loads quicker with the short arc. The j-bar made more sidebite for us as we could get more angle in it. Try moving your weight higher in the car and dropping the whole bar lower but still leave the axle side 4 to 5 ins. lower than the frame side. What spring rates are you running across the rear? Swing arm rates usually run 300 LR, 275 RR. Don,t get too soft on the RR or it won't bite because the RR spring will absorb the weight transfer instead of driving the RR tire harder into the track.

I have to aggree on the stiffer rr spring. My car was real sensitive to the rr rear bar angle and the rr spring rate. Although my problem was the opposite of yours, I usually had too much sidebite.
