I have Hotchkis Race Pack (endlinks, springs, sway bars, strut brace; I have the same grinding, chatter / rattle and clunking noises. It's been like that for quite some time, has been inspected a few times and seems to be installed correctly.
Going to have vehicle inspected "again" this coming week to make sure the springs are seated correctly, endlinks setup, and check setting on rear sway bar (which setting for stiffness).
Overall I like the Hotchkis product too in terms of the difference in overall handling, but I don't like the noises (grinding when steering, front and rear clatter / rattle from springs).
