Because they are softer than Jell-o and sag like a granny.
Says who? Jordan? Brew had a set that sagged, and Jordan thinks they suck. But aside from that, I can't figure out why they seem to get such a bad rep.
Let's take a glance at eibach's record - they seem to be doing ok in the performance and lowering spring biz. And what kind of spring do the much-desired Ground Controls use? Hmm. If those linear rate springs are so incredible, how is it that they completely dropped the ball on their progressive street springs?
I have PERSONALLY owned and driven on an eibach/bil sport combo, and loved it. No sag, excellent compromise of ride quality and stiffness, and great handling.
Fo sho? I thought these were offered (albeit rarely optioned as such) in the US.

Springs are made up of numbers, it's as simple as that. No black magic, no hidden features.
Now, Eibachs are significantly shorter than stock springs (usually 40-70% of the actual travel), and are not in any significant form stiffer. This makes them a horrible design, that only gets worse over time with their sagging.
I personally know that even a 300lb/in spring rate in the front (over twice the Eibach's) at the SAME ride height that the Eibachs provide is just enough. IE Stage III's or H&R Race's are 310lb/in, and are enough to lower a car that much. There is a reason H&R Sports don't lower a car to the extreme Eibach Pro-Kits do, it's because a car does NOT handle well at that height with that soft of a spring rate. Add that to the fact that H&R Sports are at 190lb/in (28% stiffer) yet make the car sit almost an inch higher shows just how far off Eibach engineers were when they designed the spring kit for our cars.
And Ground Control coilovers come with any rates you want. The lowest GC will sell you for the front is 300lb/in, which is over twice the rate of a Pro-Kit. Yeah, think about that one.

This is spot on. I am not saying Eibach is a bad manufacturer, just that the Pro-Kit is a shitty setup.

Thanks Jay, that was the first fact-based argument I've ever seen against Eibach Prokits ever - and it's great information.
I just go with what I've personally experienced, and to me, the ride quality and performance and ride height that the eibachs gave me was PERFECT for a daily in MA.
What should I do about my cabbie in this case? The H&R race are just too low...
Find someone who has one and check it out - I tried to get one a couple of years ago - there are NO US market 5 speed e34 tourings. None that came that way from the factory.

That's not what the dealer techs who work on them have to say. But they are pretty rare, and the manual was only available on the 525's, V8 tourings never got the option here.
