What have you found? My ride is an 02 SS and swapped from an A4 to T56 last spring and still have the 3.23 gears. This year it was good on the track however I know it will power out of the corners better with a gear change.The goal is best road course HPD experience yet still be a good dd. A gear change will be done this winter. At a minimum
3.42s but am considering the 3.73. Although the 4.10s seem like they would be fun but, I want to stay away from excessive wheel spin and maintain reasonable mpg. Mods are bolt ons, intake, fixed back seats, 5 pts, roll bar and slicks on the track.

On the road courses you will have to find a compromise for what works in the turn sections vs the goal on the longest straight and whether or not you consider 6th or 5th your top gear at the track, and which track.
At the most basic level you will experience such a small difference from 3.23 to 3.42 it would be a waste of money. Do some math to target your goals to just past your horsepower RPM peak before braking at the end of the longest straight.
What you end up with as a DD won't really make much difference unless you go the other way.

I don't agree with the idea of getting a converter before gears. When you order your converter, it will be built based on the gear ratio you are running. Why get a converter built for 3.23's, then a few months later bump up to 3.73's? The two need to cork together, and the best way to do that is to have the gears you want to run in your car when you install the converter. JMHO...

to me there are 3 ratio options for street use. 3.73, 3.90, or 4.10 I run 3.90's with my factory sized 17 inch tires, it's too perfect. I couldn't imagine the gas mileage running 4.10's, but I know some guys like them.

that chart does not seem right at all for the M6s. theres no way with 4.10 gears u can do 40 in first gear (at redline)

I've noticed that smaller motors have more aggressive gearing from the factory. Look at those 4cylinders running 4.56s

Guess it's time to welcome this thread back from the dead.
3.23 (GU5) was the highest numeric gear offering from the factory for an A4 V8 4th gen.
3.42 (GU6) could only be had stock with an A4 4th gen in V6 trim.
