I was originally looking at the same tires along with a few others and finally went with the Falken 512's in a 245/50/16 for my Mustang GT. They have an excellent price now at Discount Tire Direct and available in an H rated or Z rated tire. I have them on both of my Mustangs and have liked them a lot. Great bang for the buck.
