From what I remember.... don't you need the rear camber kit to get COMPLETELY within spec on Eibachs?
I know you can get EXTREMELY close on rear camber, to where it's just about within tolerance so it's negligible and every other aspect (toe / front camber+toe) are fine even when dropped.
As said previously, Eibach and H&R lowering springs do not require toe/camber kits, but a fresh alignment is highly recommended after installing.
