I don't want to sell these but I know most probably I won't be putting them my car. Please take them from me before I end up changing my mind again. They fit XI models.
Part number 102 20 048
They're brand new.. selling for $1500 obo. Used sell for about $1200, these are not used.
I'm not sure if it fits other BMW models but you can check it from Kw product website: http://www.kw-store.com/products.html
