RJ, I don't have a dog in this fight but I find it hard to believe a '11 GT is going 11.90's by just adding drag radials and granny shifing it. I would bet it at least has a tune and a cold air intake. I'm not saying a GT won't do it but it takes a bit more than drag radials to get there.
I have one and have been around these cars a good bit lately. They make great power but 11.90s is a bit of a stretch stock...
I still like my FE too though.....
