"GM will be offering new goodies in its performance parts catalog that allows older SS owners to build their cars up to this new, wonderful spec." Brilliant. And not something a Mustang GT guy can do to make his car a BOSS, although Ford Racing does have enough parts to come close. As always with a Mustang, it is the suspension that you'll find the letdown... roll on 2014 and a half when all us us should be rolling on IRS. Then again, with any luck I'll have my Aston by then.
