[500e]

Lowered my 08 e90 335xi on eibach pro kit on Saturday. Got an alignment today and the front alignment was -1.2/-1.0% and rear was -2.0/-2.2%.

Wondering if that's acceptable or if I need camber plates? They told me front wont need it and rear will. The camber is visibly off on the rear. Let me know your thoughts and if needed which ones should I get? Also are there any cons to camber plates? Like vibration etc?

Thanks!
