Selling my
Brey-Krause harness bar, as I've since added a full rear cage to my F30. This setup has been outstanding, as it's easy to install for track days, and remove for full use of the rear seats after returning from the track. It fits perfectly in either an F30 or F80, and is in like-new condition; totally rock solid, with no rattles or squeaks.
Can be run with the rear seat completely in place, or you can easily remove the rear seat (just a few bolts... which is how I ran it to save weight ; )
