I just replaced my rear bilstein shocks w/ a new pair of competition engineering adj. shocks in the rear. I set them to 70/30 and now the rear is bouncing like crazy. When I got them at home I noticed that you can compress the shock and it dosn't go back up by themselfs like the bilstein's. Are these broke or are they like that? should I keep these and just set them to 50/50 or should I throw the bilsteins back on and save up for some qa1?
