This is the link for the Watts bars. You can see how much punishment and hard driving BMR designed it to take with its sturdy aluminum body, large mounting bolt, and fully bushed pivot point for squeak and bind free operation.
Here the link is mounting to the main bracket. The link can be adjusted up or down to fit your car's suspension tuning and driving purpose, and any track conditions you might encounter.
With the bracket in place, the side brace arms are secured to the torque arm. These braces also help to stabilize the rear end and keep it in the correct geometry with the torque arm and Watts-Links so the system provides maximum performance at all times.
With the side braces secured to the torque arm and the Watts-Link bracket in place on the housing, the rear bolts can be tightened up.
Two additional mounting points and braces secure the link to the bracket for extra strength and stability in hard cornering.
Next up is to remove the leaf spring assemblies so the new control arms can be mounted. A pair of jack stands supports the body on the rear subframe so the leaf springs and their mounts can be removed safely. You'll also need to support the rear end to keep it in place while this process is going on.
With everything supported, the shocks are removed.
The BMR kit includes this plate to cover up the factory shock mounting hole in the body to keep moisture from getting inside the car and causing problems. Note the evidence of tire rubbing in the wheel well. With the new BMR kit, this won't be a problem anymore.
With the shocks out of the way, the spring shackles are removed, and in this case the attached traction bars. Another great feature of the BMR kit is the elimination of the inherent wheel hop problems leaf spring cars experience under hard acceleration.
With the rear end housing supported, the weight is removed from the leaf spring so it can be pulled out safely.
Up front, three bolts secure the forward spring box to the body. They're removed along with the lead springs, but will be reused later.
In the back, it's just a matter of removing the bolt that secures the spring to the rear subframe.
With all the necessary bolts removed, the leaf spring comes right out.
You need the factory mounting box of the leaf spring to mount the new control arms, so it has to be removed from the old leaf springs before tossing them aside.
