I have an Exotic Air suspension kit for sale. It came with a past e46 m3 I purchased and was only used for 10k miles. I don't know much about it other than some quick reviews online stating it was a quality made air kit that is no longer available. Condition is very clean and was working when I purchased the vehicle. The wires were cut during removal so you may have to provide yourself. I also will take the cups off my kw suspension in sale. Its been sitting in the garage for 2 years. Not sure how to price this best PM me an offer.
