Rear end not flat and clunking noise
 

This past weekend I installed a set of Eibach Sportline spring kid and BMR adjustable panhard bar. A few days later the passenger side sits about an inch lower than the driver side. Additionally when going over small bumps it sounds like something is clunking or banging. Nothing appears to be loose when I checked last night.


Any ideas? Its an aggressive height, about a 2 inch drop in the rear and 1.5 in the front.

It probably is your over-axle pipes.
