You only need one post rather than multiple over the same subject. Especially when the answer to this is easily found by using the search button.
Panhard centers the rearend. TQ arm does not. Control arms control center of wheels in the wheel wells.

He's Correct! But you will need adjustable components! What you can do is find the center of the wheel and tape a piece of string to the fender and measure out from the lip of the wheel and adjust until the wheels are the same measurement! Below is a link to show you what all Rear Suspension Packages UMI Performance has to offer!

To actually center it, the car needs to be supported on all four wheels, so either on a lift or sitting on four ramps, blocks etc . . .
Tape a plumb bob on each quarter panel. Can be as simple as a string with washers tied to one end as a weight.
Measure the distance from the same point on the wheel to the string, on each side.
Adjust until the distances are equal.
Torques arm does nothing to "center" the axle . . . .

FYI - centering by using the fenders as a reference will get the rearend centered relative to the BODY. If you measure from the inner fenderwells to the wheels, and center it that way, you will have the rearend centered relative to the CHASSIS. The first way gets you a car that "looks" good, the second gets you one that "handles" good.
When I did it the "fender" way, I rubbed tires on the right side, above the bump stop. When I centered the rear using the inner wells, I no longer rubbed.
Reason is that no 2 cars are the same. It's essential for driveline components to line up, so the tolerances on those are pretty small. But, it's not a huge deal if body panels don't line up. So, tolerances on those are larger.
