Even though I love the IRS in my 03 Cobra it took a lot of money and effort to make it reliable.
As it came from the factory all the bushings were soft rubber to make the NVH tolerable. So naturally if you got any wheelspin it would hop uncontrollably, usually breaking a halfshaft.
I replaced every piece of rubber in it with a kit from "FullTiltBoogie racing"
The Finest IRS Delrin Bushing Kit
After installing the kit I can now do a clutch drop with slicks at 5K and not break a half-shaft.
I sure hope Ford does a decent job on the new IRS.
