i kno drivin a stang isnt like other cars

do they have 2 steering wheels?????
Seriously, practice is the only answer to good launches. They are a blend of not letting the engine bog (V8 grunt helps prevent this but the 2.0 turbo ricers have loads of worries) and putting as much power to the wheels with out lighting up or frying the clutch.
Manual and auto cars are also slightly different, as a rule autos are alot easier and more consitant which is why so many drag racers swear by them. All you need to do is push the loud pedal. Well kind of, low grip and/or big power makes it more challenging.
With a manual car you want to launch with as many revs as you can with out ending up sitting on the line wheel spinning. A small amount of wheel spin is good (some say about 10%). So when you launch you need to feed in the throttle pedal while you SMOOTHLY lift off the clutch, but try not to slip the clutch too much as they are expensive to replace. Although if you do get too much wheel spin slipping the clutch will allow you to control it without having to reduce the rpm's which could cause the motor to bog down.
Any 4.6 Mustang has the power and torque to light up the rears no problem, so if on stock rubber take it easy and pull away as if from the traffic lights then nail it - get use to it then try more extreme starts and get some DR's.
Remember some golden rules:
1. More Speed Less Haste
2. To finish first, first you have to finish
Smoothness and quality driving are the key ingrediants.
