Continuing on with suspension upgrade installations for the S197 Ford Mustang, we are back to show yet another how-to regarding the installation of a set of lower control arm relocation brackets. These J&M LCA relocation brackets allow for a dramatic change in the instant center of the car, resulting in a better weight transfer to provide a better launch off the line. This original StangNet.com write-up gives a real world overview and interpretation on how to perform the bracket installation on a 2005 Ford Mustang GT. StangNet Staff member bigcat shows us just how it’s done.
Tools needed: 19mm socket and wrench, 18mm socket 22mm socket and wrench, ratchet, torque wrench, jack, jackstands
Raise the vehicle and properly support it so you can safely work underneath it.
Using the 18 mm socket and wrench, remove the counter balance weights from the rear axle, if equipped.
Remove the 18mm bolt and flag nut from the lower control arm where it attaches to the axle, and swing the LCA out of the way. The fasteners will not be reused for the new brackets.
Install the J&M relocation bracket onto the axle, over the original control arm mounting bracket. The bracket with the offset and washer is the driver’s side bracket. Insert the small nut and bolt with washers on each side into the upper mounting hole, where the weight was originally mounted.
Use the metal sleeve included, and insert it between the original bracket mounting holes. Install a washer on the long bolt, and insert it through the sleeve. Install the other washer and nut. If the nut is towards the center of the car, there is more room for your power tools. Suspension components will be in the way on the other side.
Reattach the lower control arm using the new 14mm bolts, nuts, and washers supplied. Do not torque any fasteners yet. All fasteners must be torqued with the vehicle at ride height and with a loaded suspension. J&M recommends installing the LCA in the upper mounting hole. If more traction is needed, move the LCA to the lower mounting hole, as shown in the pictures here.
Repeat procedure for the other side.
Once the vehicle is on the ground and suspension is loaded, you can torque the fasteners.
