Hey everyone so ive been looking at air suspension kits for my 2017 cla20 4matic. I noticed all kits are made for 2wd only. Is there a reason why it wouldnt be compatible both ways or anyone would know whats the difference to make it work? i tried search and couldnt find results. Not looking for opinions on if you like air suspension or not so if you dont have insight please dont spam thanks in advance!
