New in box Brey-Krause harness bar for the BRZ and GR86 (I believe this will fit first and second gen cars)
Here is a link to their website

I have never removed the bar from the box, ended up having a custom cage made, so I simply don't need it. They retail for about $750 plus tax plus shipping plus usually a few weeks wait time. I am selling for $500 plus shipping.
