I am going to get gears but don't know what to get, my car is a daily driver and I do drive on the expressway a few times a week. I do not plan on boosting the car anytime soon. I just want to give the car more pep from a take off... What do you think?

My son has been running 4.10's in his 96 with no problems.He drives on interstate several times a week and has over 100k miles. The 4.10's seem to really wake up the 4.6.

You should check this thread out ( http://www.allfordmustangs.com/forum...my-1999-a.html ) I asked a very similar question and got different recommendations, most of them favoring some 4.10s. It should help you make a decision.
