This is the Buschur Racing rear differential support, or called by some the "mustache bar". This also holds the rear differential in place. The stock bar weighs in at 15.9 pounds and ours weighs in at only 3.2 pounds, that's a nice 12.7 pound savings.
This is the part we put on our car, along with the aluminum rear differential bushings that we are crediting our new improved 60' times to.
*NOTE* - We do NOT recommend running this bar with the factory side differential supports. Doing so may result in extensive damage to the bar. We offer upgraded billet side diff supports (sold seperately). One option is solid, the other option is with stiffer upgraded urethane bushings. Upgrading to these mounts will also help save addtional weight.
