Ford Mustang GT 07 Race Tune

[drift501]

I have recently purchased a 07 Mustang from the dealership. I have done some basic modifications ( ECU, 2nd Exhaust ( forgot it's name), Catalyc convertor, Hard slicks and some other things I forgot ( doing this from my ipod using only my memory) and I have painted it, put wheels on it and a carbon bonnet.) I was wondering how to tune it to make it a circuit race car that has a bit of oversteer so at a touch of the handbrake so I can drift it.
