........With weight on the car the top of the shackle should be a little forward......stiffer springs have more curvature to them in effect making them shorter...u could always shim the rear mount to bring it forward. .kim.....
I think the shim is the next thing to try,I have tryed to jack it over and over that is as far back as i could get it.Bummer have to pull everything apart.Do they make the shim,or do I have to make them,if how, how thick 2'' 3'' 1/2''.
