which camber kit do you use ? I got my lowered car aligned at a Mercedes dealer per eibach specs and even provided them with camber bolts but they didnt need them and they were able to do the alignment. I got ~ -1.2 front and -2.4 rear camber and they also told me that they adjust some other thing so that I dont eat my tires. I think extreme tires wear are due to toes not aligned properly.I had an issue with the front when I lowered mine, sounded like a water bottle being squeezed and only happened around 40-50 degrees. Once I installed the camber arm kit in front it went away. I even had it at the dealer for 2 days and it drove them crazy, couldn’t figure it out. I would recommend camber kit for front and rear or you’ll go through tires in about a year.
