To make room for the antiroll bar, first remove the rear sway bar. The car we used for the install was Steeda's top-tier Q650, which was obviously already upgraded with Steeda's rear bar.
Less Weight, More Traction
When we returned to take the Q500 for a spin, we were able to catch up on some new Steeda gear that slants toward the dragstrip. Though the company has long been known for building gear to turn corners, its Hardcore line is targeted squarely at the dragstrip. A new piece of hardware for S197 weight watchers is the company's S197 tubular front crossmember (PN 555-5075; $179.95). This part isn't limited to racing, but it does shave off weight where it counts-the front of the car.
Truly a drag-race-only part is Steeda's S197 rear antiroll bar. Drag racers are likely familiar with these devices for earlier Mustangs. These ancillary rollbars counteract the Mustang chassis' natural tendency to load the passenger-side tire and unload the driver-side tire. The result is an even application of torque to the rear tires and quicker e.t.'s.
The antiroll-bar mount first bolts to the stock sway-bar mount. With this in place, you can use the billet mount as a guide for welding this additional mount tab to the chassis. | 
It's necessary to weld new tabs onto the rearend housing to attach the antiroll bar's spherical rod ends. Once you've welded on all the new tabs, be sure to paint these areas to keep rust at bay. | 
Here's the finished product. Steeda's in-house shoe Scott Boda has been testing this piece, and the results have been drama-free launches. |
The front crossmember in the S197 acts as a mount for the front sway bar and the cradle for the radiator. Steeda's tubular, chrome-moly unit does the job with a lot less bulk. | 
While drag racers may want to forgo a front sway bar altogether, the Steeda crossmember allows you to retain the sway bar for the street. | 
We used Steeda's in-progress road-race car for the crossmember install, as it was easier to see what was going on. As you can see, there's a lot less metal on the front of the car with the new crossmember in place. |
