#9

I was there when Ford debuted its new-for-1999 Mustang Cobra with its “revolutionary” new independent rear suspension. The IRS was a first for the Ford Mustang, and it was a move that Ford’s brass believed would allow the “new edge” Cobra to compete with cars like the BMW M3 for supremacy in the budget super car market. I also remember the very first question that was asked: Will a Ford 9″ bolt in? It was the first question, right out of the box … and it seems like someone at Ford remembers. The new-for-2015 Mustang is going to hit dealers with a new independent rear suspension late next year, and it seems like Ford Racing will have a 9″ live axle option ready.
