I posted this on the North American Motoring forum...now here for your pleasure.
Don't know how many of you are also Bimmer-files and also BMW Car Club of America members (like me ). Anyway, I just received my Nov '05 issue today, and there's a 4-page article on the Koni FSDs. Rather than an info-mercial, it's actually a test between OEM, Koni adjustables (set to softest), and the FSDs. The level playing field platform are 3 identically prepared BMW E46 coupes (same wheels/tires), and the test is run at TireRack's autocross course, a slalom, and skidpad. Well, the FSDs kicked butt on the slalom, set the best group average and average Gs on the skid pad, and set the best lap time on the autocross course. They loved them, and stated the ride quality is equal to a Buick Electra while cornering was "autocross" level. They were quite amazed and praised them to death. I'm convinced (for street use) that there's not a better suspension upgrade than FSDs-only (no springs) for those seeking better ride quality and still not give up a thing on cornering. If fact, these will enhance cornering, and still leave you with other cornering improvement options (bushings, bars, etc.) that won't adversely affect shock bump control. It's a very interesting article. Not available on news stands--sorry. Wish they used the MINI S instead of that chick car.
Here's a link (contained within) to the article as posted by another member:
