Just like most of you I was debating 3.73 or 4.10 on a NA mustang GT. I read all the threads of why you should or you shouldn't go 4.10's. I took the plunge last week and for those of you wondering still. DO IT !!!!!!!! It is a totally different car. Yes I did get FRPP 4.10's and no they do not whine. There is not a sound coming from the rear end. If anyone says different they have no idea what they are doing. Fuel economy is not that much different and it does wake the car up. It is a worth while upgrade for any mustang. especially if you have a 5 speed. Hopefully this helps those of you still trying to decide.
