I've recently started 1/4 mile drag racing. I notice that during burn out at the track, and when I do a burnout on the street, that the rear end immediately starts moving to the left and does not track straight during burn out like the other cars at the track. I have a Ford 9" rear end with 2 trailing arms, a Panhard bar, and a 3rd link bar. What adjustments could I try to get the Cobra to track straight during the burnout?
