I a n00b when it comes to stangs so bear with me if its already been covered in depth... Correct me if I am wrong but I understand that the '03 cobra has an IRS. So why the heck couldn't Ford carry the technology forward and place it in any of the '05 mustangs. Again correct me if I am wrong, but the GT500 will also have a live rear axle. Its supposed to be faster than all mustangs of past, why not make it handle better also...or is there something I am missing about these new live rears...?
