Go for it, i personally would save the extra money, it might take like one more paycheck of work? and get the good trusted brand, they say aprox 2" drop, sounds like they havent even tested them on a mustang. Though all cars are different id rather know proven numbers on the drop in the front and in the back. And know one will know the qualit till you get them, and see how smooth the car really is. I personally would go with the known brands and pay some more money.
