My car is a Ram SC, and the design was endorsed by Shelby from 1992 to approx 2002, being an english car, is naturally setup for the Jaguar IRS, I have an alloy Ford 8.8" IRS that is being fitted to this chassis with all new axles and suspension arms, YES a lot of work!!!!!!!!
The reason is that in my opinion the Jag IRS is far to heavy, and in my last Cobra I kept screwing the Jaguar outer coarse 10 spline hub axles, yet quite a few people seem to run up to 800bhp with no problem.

So generally the Jaguar IRS is very good and as in a Cobra if you have the double wishbone like an original they work real well, and you can get moly outer axles etc for them. I am not that keen on the 8.8 IRS inner plunge joints, but we will see everyone says the Cobras weigh half the weight of the Thunderbird etc.

In the kits here in NZ, the Almac Cobra when racing on high speed air force bases the Jaguar diff can be unstable on high speed turn, a few guys have gone to Nissan 300ZX viscus diff with double wishbones, but you aint going to do that with a CSX or Kirkham, a much stronger diff than Jaguar or Ford 8.8" with a larger crown wheel etc!!
