How about some numbers, or a picture, or at least a description of which end is higher, or if it's just one end or both. Most people with Eibach problems say the front sits too high.
Could be that somebody made a large batch of counterfeit Eibachs and the dealers just keep buying them. With all of the bad press it's surprising that anybody sells them, and that people keep buying. I guess the second drives the first.
Also, did you check that the stock springs weren't cut? Maybe you're comparing new Eibach to cut stock.
