lol, if its a GT that the op has, i will slap you for trying to through a 7.5 on there, i frankly woulkd try other options for your car. try lighting it up, throw a dual exhaust on it, a CAI, under drive pullies, lower it, get some nice wheels on it


and bam, you'll have a decent car


plus, you will somehow have to re calibrate the car, since it will be a different gear ratio, which costs a lot of money

i say, go to the website i gave you, and give in to the dark side of the force
