It’s easy to get caught up in the excitement of the latest IRS-equipped Mustangs, but if you are still rocking a 2005-2014 Mustang and you like turning corners, you might want more lateral control from that live rear axle. Upgrading the factory Panhard bar is one way to go, but if you want the ultimate in lateral axle control, a Watt’s Link is the move. And, there’s a new option available from BMR Suspension.
“A Watt’s Link is the superior way to laterally locate the rearend housing under the car. It’s more complex than a simple Panhard bar, but the difference in operation and the level of effectiveness between the two is about as distinctive as the differences in design,” Pete Epple, Marketing Tech at BMR Suspension, said. “A Panhard bar is designed to minimize side-to-side axle movement. But when you traverse imperfections on the road or make turns, the axle shifts slightly to one side. This is because the Panhard bar, by design, travels on an arc, allowing the axle to shift slightly to one side during normal suspension travel. For most casual enthusiast, this movement is never felt or noticed, but it can cause the car to have a slightly disconnected feel in certain situations when the axle moves.”

So, while BMR already offers an adjustable Panhard bar for the S197, they decided to develop a new Watt’s link for those looking for optimum lateral control for their live-axle 2005-2014 Mustangs.
“A Watt’s Link, on the other hand, mounts the rearend housing to the chassis with two equal length links and a center pivot. This keeps the rearend housing centered no matter where it is in the suspension range of travel. The system can be configured in one of two ways—either the pivot is mounted to the rearend housing or the chassis,” Pete added. “If the pivot is mounted to the rearend housing, the links are mounted to the chassis. If it’s mounted to the chassis, the links connect to the axle tubes; BMR’s WL005 and WL005 are this type. As the rear suspension travels, the pivot rotates, keeping the rearend housing centered under the car.”
Built from steel tubing and a laser-cut steel plate, the BMR Body Mount Watt’s Link is available with either polyurethane bushings (PN WL005; $549.95) or rod ends (PN WL006; $549.95). Both configurations offer bolt-on installations, but the poly version features rod ends at the pivot and poly bushings at the chassis mount to reduce noise, vibration and harshness. Meanwhile, the version with rod ends on both ends of the link offers maximum control and adjustability in trade for more NVH.
Either is available in red or black hammertone finishes and can be installed in three to four hours. We wanted to see how the new BMR Watt’s installs, so the company was kind enough to document the process for us, and here we are hitting the highlights of that process.
