Here you can see how the box is bolted to the forward part of the new control arm to mount it to the body/subframe.

In place of the old spring shackle is this BMR unit, which not only connects the control arm to the rear end, but also serves as the lower mounting point for the new adjustable coilover shocks that are replacing the leaf springs.

A bushed heim joint is on the rear end of the control arm, allowing for bind free movement, and added length adjustment for increased suspension tuning.

Next up is to install the upper mounting bracket for the Watts-Links and coilover shocks. The first thing to do is set it in place, and use the included self tapping screws to hold it to the subframe while the other mounting pieces are put in place.

Here you can see where the outer mounting bracket will attach to the outside of the rear subframe. It's always good to set things like this in place first, measure and check alignment, then make marks for drilling, so you get it installed the right the first time.

With everything marked, holes are drilled in the subframe for the mounting bolts. To make this process easier, using a step-style drill bit will save you some effort, and make sure you don't drill too far.

Part of the reason for drilling such a big hole in one side of the frame is to allow the installation of this small brace. This piece will keep the frame from distorting when the mounting bolts holding the upper bracket are tightened down.

The easiest way to install the outer part of the bracket is just like this, that way the two cylindrical braces don't fall into the frame, and you can make sure everything's lined up properly. Once this part is in place, tighten down the bolts, and the upper bracket is installed.

With the upper bracket secured, it's time to assemble the new coilovers. The BMR kit comes with QA1 adjustable coilover shocks that allow for even more suspension tuning. The shocks are super simple to assemble, just slip the spring over the shock, then the top collar, and tighten the collar down, you're good to go. Once the car is back on the ground, then you'll want to follow the BMR and QA1 instructions for properly adjusting the spring on the shocks.

With the shocks assembled, they're ready for install. A drift comes in handy for getting the shock lined up with the bolt holes on the upper bracket.

Here you can see the very sturdy lower shock mounting. Under hard driving conditions, this part sees a lot of stress, so BMR designed it to be plenty strong.

Here's how everything looks with the shocks installed. The last part that remains are installing the Watts-Link bars.

Installing the Watts-Link bars is easy, the just slip into their intended brackets on the upper mount. The BMR kit includes instructions on which mounting/adjustment hole to bolt the bars to when first assembled, and how to adjust them once the installation is done.

On the link ends, the bars use heim joints for bind free operation and additional adjustments. Like with the rest of the kit, heavy duty grade 8 bolts secure the bars in place.

Here you see how sturdy and secure the Watts-Link bars are connected to their pivot point. Depending on the handling of the car, track being driven, and overall driving intent, the pivot can be moved up or down to change the roll center as necessary for optimal handling.

Here's how everything looks in the rear fully installed. To start out, the Watts-Link bars were set in a neutral position, with adjustments to be made after the car was back on the ground and driven a little bit to evaluate what changes were necessary. When you reach this point, all that's necessary is to reinstall the gas tank, fill the differential, and bolt the wheels back on.

Here's an overall shot of the whole BMR Torque Arm/Watts-Link kit fully installed. From this view you can see the strength of the BMR kit, and how cleanly it installs on the underside of the car without any major modifications. This whole kit gives the best of both worlds when it comes to handling, allowing a car owner to have great road handling, and great strip handling when necessary.
