[Red Mustang Gt 46]

Blake...since you mentioned your wife driving the car...with 4:10's your shift from 1st to 2nd is going to be rather quick. Some who are not "into" performance driving can get annoyed with this. With 3:73's I doubt that your going to notice a big difference.

IMO, I would still go with 4:10's...don't be scared it's going to be too much...cause it ain't. As stated before, you will smile for months...
