3.73s

I have a 97 a4 and want to put some 3.73s in it to give it some more power. Anyone know how much it is to install these and if I'll need anything extra to have them isntalled. Anyone also know where I can buy the 3.73s?

Also, The gears don't add power but will make your car a lot quicker.

gears will not give you anymore horsepower,,just quicker acceleration. Think about it as if you were starting out in 5th gear on a 10 speed bicycle. verses starting out in 1st gear on the same bike.. A lot less effort and energy is required for initial acceleration
