I spent the day in the garage today. Nothing like 100+ degree temps and monsoon humidity to make for a great day in the garage. First few hours were aimed at trying to clean up a bit and organize. The last few times I've worked on the notch I've sort of left things in disarray. It's still a mess, but less of a mess.
Around 3 p.m. I started on the brakes, and called it quits around 9 p.m. My girlfriend kept distracting me all day to help her with some yardwork, so I didn't get as much dedicated time as I would've liked. Anyway, here's some progress...
My rear brakes were totally shot. The car only has 16,000 miles on it, so I find this very odd; however, the dealership says "with these new ABS units" this is common. I dunno, but that's for another tech thread. So here's some pics of the OEM rear brakes before I started the tear down. Notice the damage to the rotors.
Here's the OEM panhard bar and diff cover. Since my car is lowered a bit, my axle isn't centered.
Factory 3.73s.
My new adjustable panhard bar from Freedom Racing with urethane bushings to cut down on NVH (versus heim joints).
After some work and a bit of a mess, the axles came out.
Old brakes and axle brackets removed. I pulled the anti-moan brackets after I snapped this picture since they're not used with the new axle brackets.
New, much larger axle brackets installed. Since my car is an '11 GT, I didn't have to remove the calipers. They are the same as the '13 GT500, so I figured there was no point in installing the new ones and having to bleed the brakes for nothing. Now I have an extra set of calipers.

I was going to powdercoat the brackets myself, but since I have to drive the car to work on Tuesday, I decided not to go to all the trouble of getting out all my powdercoating stuff and having to beadblast stuff.
Here's the old rotors vs the new hotness. They are huge!
I got the diff buttoned back up, (except one bolt, which I'll explain later) and the axles, rotors, and caliper anchors all installed. Tomorrow I'll run to AutoZone and get some nice quiet new street pads, then finish the calipers, and fill the diff. Once that's done, I'll get the new panhard bar put in, and adjust to get my axle centered in the chassis. If time allows, I'll clean up the wheels a bit, and get a carwash.

Overall, the job isn't really that hard, just a bit time consuming. Especially when you're doing it by yourself and have to get up and down from underneath the car a bunch of times. Regardless, new cars are WAY easier to work on than my stupid old notch.
I'll get all the finished install pics up tomorrow hopefully.
