I have for sale a KW V3 coil over suspension kit for e89 Z4. Done about 1700 miles in all, mostly on track days, does height adjustment rebound bump etc. Does not have the electronic box for adaptive suspension cars so will show error sign on dash but no problem with operation. Think it cost me about £1800 new plus fitting etc so I will ask about £500 but that price is very negotiable.......very. Also have a RACECHIP remap module for e89 Z4 30, 35i and 35is, plug n play just unplug before any dealer work, cost was about £480 new I think so will ask about £100, again negotiable. If bought together you get a free tailored e89 car cover.
