I am not exactly new to gt but to tuning, I am clueless but i want to know more ( that is anything ) I know nothing about tuning a car on gran turismo and i would really like to. I have example a gt40 and want to improve the handling but i dont have a clue how to. I put racing brakes and a controller on it for it but they still suck and have to slow down on any corner... All i thought you could do was buy turbo, tires, exhaust... but i didn't know you could tune it to the way you want. Not a single website is telling me how to either and i hope somebody can help me? Please?
