30,000k's here, got some rattles from the back at highway (ie 150km/h ) speeds, think its either the rear seat belts or rear speakers (have premium sound) as its coming from both sides... also I still think I have brake issues even after its been in multiple times, as I can hear some rubbing from the right rear at speeds below say 20km/h, like a steam train because its only rubs for a small part ofthe wheels rotation.
