Wrong. The IRS in the Terminator Cobra was a good system. It was built to do road racing style driving, and it that regard it did very well. The problem owners had were that most were 1/4 racers. You do a a chip, pulley, exhaust and you were already at 450~475 RWHP. You do a swap, to say a KB or Whipple, now your over 600.
The STOCK IRS was not built to hold that type of power to drag race, and many were breaking the half shafts at the track. I saw one implode myself at the track. So since many mustang owners are 1/4 racers, or do 1/4, they did the swap to live axles on their Cobras.
When the 2005 was being design, Ford put a survey out to many Cobra owners, including myself, as with other Mustang enthusiast. The response came back to have the live axle put back in the Mustang. So Ford has come up with what currently resides in the s197 platform. Which is doing quite well.
