Don't these type of uppers create a problem for street driving or are they rubber? I would like to use the same panhard bar and lowers, but with a torque arm setup.
Plagiarized from MM:
The best compromise between resistance to suspension bind, best control of axle position, best ride quality, and least potential damage to the chassis, is to retain rubber bushings in the rear upper control arms. This is especially important when adding a Panhard Bar. The compliance of a rubber-bushed upper control arm is required when a Panhard bar is added to the Mustang four-link suspension.
The Mustang's rear suspension design forces the upper control arms to perform two jobs at once. They control the side-to-side position of the axle housing, while also preventing axle-housing rotation during acceleration and braking.
The Mustang upper control arm design fails to perform either job well. This design causes binding of the rear suspension that not only leads to poor handling and traction problems, but also damages the upper control arm mounts on the chassis.
A Torque-arm Suspension System replaces the troublesome upper control arms with a Torque-arm and Panhard Bar. This separates the two functions once performed by the upper arms. The Torque Arm controls axle housing rotation during acceleration and braking, and the Panhard Bar controls the side-to-side position of the axle housing.

Hi Tony,
you need to remove the upper control arms with a torque-arm setup.
Not in my case.
Check MM Torque-arm FAQ: for more info.

Do I have to remove my upper control arms after installing a Torque-arm?
Hey Tony, nice motor setup ... how much hp/tq?

- Yes, the upper control arms must be removed.
- The Torque-arm is not an add-on traction device. It is a fundamental change in the rear suspension design.
- A Torque-arm suspension is a variation of a 3-link suspension. Plus a Panhard Bar.
- Leaving the upper control arms in place would cause massive suspension binding because you would have both a 4-link and a 3-link suspension on the same car, with both systems trying to cause their own particular rear suspension motion.
