    8.8 ford solid rear end

    Can a 2003 mustang gt rear end fit in the 2006 cts v?? What needs to be done to get it in there? Or would keeping the stock rear end and having braces and what not on it it be better?

    I have a 99 cobra that I'm parting out and I switched out the IRS with a solid and I'm parting the car out so I have this rear end and now I'm Thinking I could possibly put it in the cts v. Im new to this car so what needs to be done

    It'll bolt right in. GM designed the Sigma platform to allow you to swap in a Ford stick axle with no modifications at all.

    lots of fab work for the SRA, the IRS would be so much easier. fuel cell in the trunk and fab up mounting points for the upper and lower control arms. no one has done one that i know of, be the first

    Are you being sarcastic?

    So you have to have the bracket setup to install it. Will the stock cvs work or will I need aftermarket ones. Anyone have experience with what I'm trying to do

    You have to have a bracket kit to install the 8.8 IRS center section. To install a 2003 GT's solid rear axle, which is the question you initially asked, you would have to completely redesign the rear end of the car. I would think that's obvious to anyone who has the slightest idea how cars are put together.

    With all the work that would be required, it would be smarter to put an actual drag-optimized 4-link in rather than the Mustang's bastardized Quadra-bind setup. Or just buy a car that is good for drag racing rather than a heavy ass luxury sedan with a fragile diff.

    DO you still have the IRS stuff? If so, I will take it off your hands.
