What rear end set-up would be best

[revhead347]

Ok, thanks. Just never heard the term "New Edge" before. I can't see why it would be any different in a newer Mustang, the axles are essentially the same.

You would think so but if you do research you see the new edges have a lot of axle bending problems. Every friend I have with a new edge gt that has any kind of power on a decent tire bends the stock axle.

Probably a manufacturing defect in the later years. Weld the shafts to the pumpkin, and that problem will go away.

isnt the diff girdle supposed to help with that tough?

A differential girdle is also a great investment. However, it doesn't keep the shafts from moving inside the pumpkin. The two shafts are only pressed into the pumpkin.

Well I have the diff girdle, the upper and lowers. Was looking into getting the brace for the tubes. or is it just better to weld them. Only concern with welding the tubes is that I have heard that if not done right they can warp the tubes.

That brace has to be welded onto the axle, and I'm sure it works great, but it's a little overkill for anything slower than an 8 second car.

Here is the deal with welding the tubes. I had heard for years that you had to put the axle in a jig to weld the tubes so that the heat would keep it from bending. Then I saw an article in MM&FF about welding tubes, and they had gone to the company that does the largest number of these 8.8 axles (PRS I believe) for one of their project cars. I clearly saw in the picture that they had the axle sitting on two jackstands and just welded all around it. Obviously curious about it, I called PRS, and they said they have done 100s of axles, and never once put one in a jig. They told me that as long as you go nice and slow, with a MIG welder you aren't going to bend a tube.

Well the brace goes bolted where the dog bone is and gets attatched to the tubes with clamps that look like the ones that are used on exhaust. As far as spinning the tubes I have seen a few new edges that have bent the tubes with bolt ons nitrous and 4.10's. So I would rather be safe then sorry.
