I have a used set of genuine BMW silver aero style roof rack load bars for the E91 chassis cars (that have load bars installed). Comes with both the racks, locks/keys, install tool and the manual.
We purchased as a gamble in hopes it would fit my parents E83 but we took a loss on this one (2" too short)
