Found the photos of the rear shock towers and the reason I think the rear bar is useless.
This is the rear frame the rear strut mount actually bolts on both side make the brace the actual rear bar
As you see the frame goes across all the way to the other side
And here is the other side
All the greddy rear bar does is bolt to the rear two bolts on the strut mount. I don't think there is any use in our car for this product which cost 100 dollars plus shipping. But I could be totally wrong. The Greddy Bar does look good and that is good for show judges.
