if u revise ur 2nd gear ratio only,and leave all the other ratio standard u wont get a balanced power transfer. Dats why its best u leave all the gears ratio standard and revise ur final drive coz the final drive gear affects all the other gears.Do you have Gran Turismo 4 game 4 da PS2 if u hav u try play that game and mess around wit the gear ratio individually u will undrstand what im talkin about,if u want wider ratio u need to widen ur 1,2,3 gear then u will get balance 4th and 5th is usually narrower.
