If you are wanting to upgrade all of your factory suspension components then you need an upper panhard bar brace. I came across the Granatelli Motor Sports Mustang upper Panhard Brace. This is a direct OEM replacement.
An upper panhard brace helps reduce wheel hop and chassis flex, and improves handling. The Granatelli brace is made from HD tubular steel w/precision welds. If you lower your car then you need an adjustable pan hard bar. Granatelli makes these also. You will also want to upgrade the upper panhard bar brace. The panhard bar brace sits above the panhard bar and helps keep the rear end from flexing side to side.
You can see it here compared with the factory Ford Mustang Panhard Brace. The solid tubular steel is much stronger than the factory ford brace.

|I have my panhard bar out for another project I was doing at the same time but this end of the brace rod just slides in and you run the bolt through it and tighten it down.|
|Then put in the two blots on the drivers side.|

Here is a shot of the brace (top) with the panhard bar and sway bar back in place. Also note the extra black Swarr bar.
Overall I like the Granatelli brace and would recommend it to anyone looking at this modification.
