For all of you who are just starting out with your 99-04 GT and want to run 13's here's a list of mod's that actually work. First off you can run 13's with the stock factory power so if you are on a budget you should resist temptation and not buy the small power mod's that you see in all the magazines.

If you car is an automatic you don't have to worry blowing up the rear end so don't spend your money on axles or a aftermarket differential.
Auto mod's
tranny cooler 50 bucks and easy to install
torque convertor 3200-3500 stall approx. 800 bucks and not so easy to install
gears 3.90, 4.10 or 4.30 (3.90's will allow you to add a power adder down the line)
Tune this is a must with an automatic ( I recommend SCT)
drag radials ( Mickey Thompsons)
These mod's will put you into the 13's

For a manual beef up the rear
Detriot True Loc and 31 spline axles
4.10's
shifter
drag radials
That will get you your 13 second time slip

With either type of car I recommend getting full length sub frame connectors welded in (about 250 installed)
