I really don't like the Ford GT. It's a nice car, fast, manuverable, but the brakes are terrible in my opinion. When approaching a 90 degree turn after a long straight, unless you brake very early you will slam into the wall. I bought the car for the supercar races and some American hall stuff, and I really wanted to like it, but it just wasn't working for me.
Now I've heard that the GT's brakes are "so good" that they lock up if you slam on them. I was braking the same way as I do any other car, but for some reason the GT was different. So I tried applying them slower and there was no difference. It's been sold.
