its not the brake line brackets catching on one another is it? i know that BC and Meisters coilovers do this, maybe these do it too. failing that change your topmounts. I fitted corolla gti complete shock assembly on my newer corolla and they did this, i changed the shocks from the newer ones with the springs from the corolla gti and it solved my issue. however your rears should not make any noise and theres no turning motion.
