After watching the video, I googled , Mustang torque arm and found some posts on another forum The OP had the whole Cortex watts link with a torque arm, and the adjustable LCA, and he raved about how good the set was, for straight line as well as the twisties. It seems like it is not cheap, but then again what really good stuff is. guess that was just a long winded bump, as I'm sure you found the same posts. lol

So what is a torque arm? I am looking and trying to find one but they are for the 04 and earlier models. Maybe he meant the watts link? I just installed a watts link and the way he described the vehicle is spot on for a watts link. The rear end doesn't feel like it's going to slip out from under you and it helps with steering in the corners. You'll find yourself turning the wheel less because there is much less under steer.

Torque arms prevent the axle from 'torquing' around the wheel axis of rotation.
For every action, there is an equal and opposite reaction. To simplify the entire chain of actions and reactions, when you step on the throttle, that exerts a force that causes the wheels to rotate. There needs to be an equal and opposite force that keeps the entire axle from rotating in the opposite direction. this is the duty of both the lower control arms and upper control arm on the stock suspension. A torque arm can replace the upper control arm and handle that duty all on it's own.
A torque arm is fix mounted to the axle itself. It's a sturdy lever arm that extends forward of the axle and is then mounted to the chassis via either a bushing or rod end, typically up near the tail end of the transmission.

I installed the Cortex watts link, torque arm and adjustable lower control arms.
The handling is really solid and stable. It feels like the car is smaller and tightened the handling. I've only had it on the streets and twisties but Sears Point is next month and Laguna-Seca the following month.

I had my first track day at Sears Point last weekend. The car felt tight in corners, minimal roll. Exit speed increased and overall balance was spot on. I moved up to the next run group because I was passing a lot of cars. I was able to threshold brake harder and late apex corners, especially Turn 11 and track out to the K wall with no sliding. I'm so impressed with this set up. It is a solid platform for both canyon carving and road course driving.

Check the Cortex website. They have a video. I noticed in your signature line that you have a Fays 2 watts. The torque arm was not compatible with my Fays 2 and had to upgrade to the Cortex watts link.
