The rear suspension is getting the Maximum Motorsports panhard bar kit, lower control arms (sans spring mount), Koni SA coil over shocks w/225# Hypercoil springs, Cobra / Mach 1 disc brakes, new 3.73 gears, axle bearings and seals as well as a new aluminum driveshaft.
The first order of business was to get the car on jacks and positioned so I could work on the rear. Off came the tires and then proceeded with disassembling all the brakes, shocks, mounts, LCA, sway bar and anything else in the way that needed to come off for the new parts.
Mustang rear axle work ready to rebuild.
New Maximum Motorsports LCA compared to stock LCA.
New Panhard Bar shock mount and LCA on left side.
Ready to pull axles. "C" clips removed (cover off) and old stock brake caliper bracket still on.
Fitting Panhard bar to frame on left side. This does take some time and an extra set of hands is very helpful. Maximum Motorsports instructions are very good. I wish I wouldn't have taken their suggested length off the bracket insert into the frame. I needed to use all the spacers and the insert could've been left 1/8" longer. I may pull this out later and change.
Panhard bar bracket on right side. You can see the spacer between the mount and frame. This is to take up any slack when mounting. Notice the Quad shocks are still attached, they are being removed.

After my first track day (in the rain) I noticed I needed more ooommmppphhh! coming out of the corners. The car came stock with 3.27 gears and decided to change them out for some 3.73 gears. After returning home from the track, I put the car on the rack and removed the rear axle to change out the gears. At the same time, I installed new stock upper bushings in the rear axle along with replacing the UCA's with new stock ones. The reason for the stock bushings is running the new LCA's with Polyurethene bushings, the stock rubber will take any added tension and allow the axle assembly to move a bit so you're not surprised by the "bite" you may (most likely) encounter when loading / unloading the car in corners. Rear axle was cleaned and painted as well when I had it on the bench. I had a choice of a Heim joint setup but decided to use the rubber, mainly for street use as well. It's not "totally" a track car....yet?
New bushings installed in rear axle housing. Tool purchased at Maximum Motorsports made the job very easy. Axle was out of the car when this was done.
Stock upper control arms as recommended by Maximum Motorsports due to the LCA's having urethane bushings.
