I installed the CPP mini sub kit on my 66 with new upper bushings and ball joints. I tightend the control arm bushes with the weight on the vehicle. My front suspension has become so stiff I can hardly move it when trying to bounce it like you do when checking shocks. (with all of 230lbs. of body weight). The car is not riding too harsh it just won't bounce . Am I too tight somewhere? It bounced normal until the "upgrade".
