Lowered and KMAC full kit installed noises driving me nuts!!!
Yes on inspection can see the problem Align shop has fitted incorrect rear kit (502226K).
Align shop should have easily picked this up as 502226K instruction sheet clearly states your AMG model (alloy not steel arms / and with inner mount slot) is #502326-1K.
502226K sheet also clearly depicts steel arms minus these slots !
Have forwarded you the correct 502326-1 AMG kit to resolve the issue.
