These are reproductions of the factory braces that were standard equipment on all Grand Prix's with heavy-duty or performance suspensions—they stiffen the chassis from the lower rear control arm forward mounting point. This triangulates this area and prevents the upper crossmember from flexing and possibly breaking. An easy bolt-in that’s noticeable right away.
