I bought this unit from member Beemer Guy a while back but never installed it, as I realized after driving a car with this setup that my current SSK was shorter (which I like). I was told that is has about 5K miles on it. It comes in the original UUC box with all the parts (even has the stickers and I read on the ricermods.com that they may be good for 2-3 hp). The kit does not include the DSSR, but that can be purchased separately. Asking $150. Thanks.
