| Whats the difference between IRS and Live rear axel
Pretty much.... why do people always gripe about the cobra's having IRS? I know the IRS likes to break under hard drag launches but I don't know why. Can someone explain?

The half shafts on the Cobra IRS are smaller than the single live axle on a GT. The trick is that the IRS in the cobra handles way better. The cobra is pretty much set up for the twisties, not a drag track.

The wheels tend to hop more with irs but when they're connected it makes it more difficult and gives you more traction.

One is better for the drag strip, the live axle, and the other the IRS Cobra rears are for a road course. I have friends with Cobra's and they don't like the IRS to soft with the rubber bushings.

I know that IRS doesn't seem to be as well on the drag strip. Which made me wonder why Ford would put it in the cobra. It seems that people are more interested in drag racing the cobra then road racing it. They should have added a live rear axel as an option.

Drag racers by GT's because they are cheaper to buy and are going to mod it anyway.
Ford from the very beginning built the Cobra to compete with the european cars that are all set up as road course and better handling cars.

the IRS is nice for a smooth ride and handeling, but if you drag race an live axle is the only WAY to go, along with the fact that a live axle can be made to handle better than an IRS probably... you just pay for it dearly with extra noise and rough ride....
