Would there be any major benefit to doing this? I mean I have heard alot of cobra owners take this out to replace it with a solid axle due to axle hop, less weight and broken half shafts. I have thought of doing this more than once but all I hear is bad things about the Cobra IRS. What are the pluses of doing this?

If you're looking for just a straightline car, then yeah the IRS is not ideal.  That's why alot Cobra owner's swap it out....they spend all their time at the dragstrip. 
Better ride and a more balanced handler are some plusses.

Out of the box, the Cobra set-up is a big bundle of compromises.  With some mods it can be a decent performer, but still limited.  Most of the bad stuff is related to how it had to be designed to fit in the Mustang chassis w/o mods (from a live axle) and to keep it soft enough for the tender asses of "most" Cobra buyers......

I've been planning this for quite a while. Need some other work done first but I can get the whole rear for around a grand or less.

It all comes together very well, considering the rear end has been in his car for a while now.
It's Gumby's fault.

the factory TC cables are still in there, and reach the calipers fine on my setup.

i do not have them hooked up to the calipers themselves at this point b/c i think i have a frozen cable someplace in the system and i havent diagnosed that issue yet.


what kinda problems are you havin?
