Anyone ever do this? I know it is possible. I was thinking of doing it in my Cobra. Any pics of before and after?
Correct, I think it is about an inch and a half wider for the 99-04 than the 94-98. It makes the tires a little more flush or should with the body lines.
I already have my suspension for the car and an IRS is not so great at the power level I want to be at. At least not the IRS we have to use.
It bolts in, is 3/4" wider per side. The lower bolt holes are larger, so you will need to change the rear bushings in your lower control arms, or use lowers from a 99-04. It fits, but I don't see any advantage too it. More rotating weight and more unsprung weight, not to mention changing the front and rear track width. I'm actually going the opposite way and putting Fox length axles in my '94, and changing the front lower control arms to Fox width. Cut down on unspung weight and allow a better offset on the rear wheel, and tuck the fronts under the car more.
Not true. They can hold the power with the proper upgrades. One example: https://www.youtube.com/watch?v=NygBzdg8cUA
But you want track width for better handling, no? That is a benefit, same with using wheel spacers to maximize the width.
I am a drag racer, so I always think along those lines. But even at that, why not run the shorter axles for less reciprocating weight, and just change wheel offset to adjust track width?
