O-Bar Torsion Bar Stiffener

The O-Bar is an alternative method to effectively reduce the amount of roll in the rear half of the car. Unlike the conventional anti-roll bar, which are bulky and heavy, the O-Bar is bolted into the torsion beam using 4 bolts.

The best site to have information on the O-bar installation is this URL bellow:

The only thing I would add is to use a strip of 1" masking tape to outline the O-bar holes, then determine the "center" of the bar (i.e. measure the midpoint on the masking tape.). Then go to the torsion bar and measure the midpoint of the torsion bar and mark it too. Then take the tape to the torsion bar and line up both center points. This gives you a good reference point when it comes time to clamp the O-bar to the torsion bar for drilling. I've added just a couple of pics I took upon installation:
