We just found a pair of our NLA rear height adjuster hiding on a shelf. Fits all E8x E9x and F2x F3x F8x. Fits 60mm springs.
One is just a display unit, and the other was a prototype(slightly different in the collar height and design). Both are functional, new, and never installed on a vehicle. The pair of height adjusters will come with slightly used thrust bearings.
Our height adjusters were selling at $200, and BMW thrust bearings at $46 for the pair.
Price includes USPS shipping to the US48 States.
