If a new rumor is to be believed, it won't have to. Ford is said to have a solution: to offer a 2015 Mustang "body in white" with the independent rear suspension replaced by a 9-inch solid rear axle. If this bit of gossip turns out to be true, expect to see the drag racer-friendly SRA Mustang debut sometime next year. What's more, Ford could very well end up selling the SRA as a kit through its Ford Racing program. This would enable drag racers to make the mods on their own without involving Ford dealers.
