It's a design flaw... I'm convinced KW just phoned in the design for the E89. KW advertises progressive spring rates, which is a great idea, except the way the build adjustment into the front coil over(by compressing the spring, instead of shortening/lengthening the strut tube), the softer coils get compressed out and it just becomes a stiff static rate. Same thing in the rear, except now your just bouncing on less than an inch of spring movement.
