it sounds like metal on metal ....sorta like when your brakes get into your rotors i can only hear it off the throtle slowing down cause my car is so loud so before i called the shop i looked under the car to see if everything looked normal on the outside and i pulled my self under the car and touched the rear cover doing so and it burned the **** out of my hand is it normal for the rear cover to be so hot? also while doing the 12 bolt i added an adjustable panhard rod and i noticed when i pulled the car in the garage for the night the right side (pass side) was noticably higher than before?

 

Did you set the adjustable PHR to the same length as stock? It would have to be way too long to actually force the passenger side of the car to raise up. And the body on the drivers side would probably be against the outside edge of the tire, with a huge gap on the passenger side.

Sounds like maybe a bad bearing or bad clearances in the Moser. Some people have had the Moser setup checked before they installed the rear, because it isn't necessarily perfect from the factory.
