Every site or review I read on the 2011 gt theres always some idiot moaning about the mustang not having an IRS. The 2011 gt out handles or handles just as good as a ton of cars that have the almighty IRS. I don't get it, why turd the mustang up with all the extra weight of the IRS. Its a muscle car and a true muscle car needs to be able to launch at the drag strip. End rant.
