Yep, agreed. But it is about weight distribution more than just the total. 540i is neavier at the front than 535i for instance, but it has a much heavier trans. It should be good. Eibach do special springs sets for Tourings with SLS/LAD, do they not do them for non-LAD cars? They should... but anwyay, for sure 530i/535i struts will work and fit well.
