Almost no one has the Eibachs. Or if they do, nearly no one comments on them.

The H&Rs are cheaper and include lowering links. The Eibachs are for non air-ride rears, which mean they come with 4 springs. Cost to lower is higher still for the Eibachs as you'd have to purchase a set of lowering links for the rear air if you have that option.

I'm almost swayed to purchase the Eibachs just to see for myself if they're good. Some owners of the H&Rs don't like the harshness of the ride, where a nebulous Eibach comment I ran across said they ride better than the H&Rs.
