Hello all, I drive an 07 e92 335i. I recently (1 month ago) installed some manzo lowering springs. Immediately after installing I am getting a severe thumping/rumbling/vibration from 0-25mph. Once I reach 25mph it stops and the car drives perfectly, it happens every time I start from a stop or slow down without fail. I have checked every single bushing down there, as well as the diff mount and subframe mounts. Everything checks out and I'm totally stumped, also had it on the alignment rack twice since and that didn't help the issue at all. Any ideas or anyone ever dealt with a similar issue?
