Changing 2:73 gear to ? 2003 Coupe
Next week I am going to change my 2:73 gear to 3:? gear. Right now my 2003 Coupe is bone stock. Any recommendations from the experts will be appreciated.
Thanks Rock Doc (Kevin)

IMO; go no further than the 3.42 if you keep run-flat tires on the car.
Also, go no-less than the 3.42 either.

I would go with no more than a 342, otherwise you are going to need better/bigger tires. Also I don't know if I caught wich tranny you have? If you have an A4 you'll need to get your shift points & comoputer re-prorgrammed, if you have an MN6 then youre good to go.Good luck

All The "Gear Guys" are checking in!!!
Hello Mitch and Mike. I also have had 3.15, 3.42, and now 3.73 I mostly do local street rodding around. I did take a 200 mile trip in August with no problem what so ever. I am stock except for a small PT2400 converter and the gears.
If more than 33% of your driving is highway - 3.42 If you think you will do heads, cam, etc - 3.42
But if you want a "stock" engine car that is real quick - 3.73 but no more. As for the tires comment - the first few months I burned a lot of rubber just giving demos to friends - my car will lay from 0 - 60 and start back up again after shifting into 2nd. Not that itch has been scratched, I never have tire traction issues.
It is just a matter of how quick and how far down you push the peddel.
But I know that I can really jump if I want to - I just do not need to as often any more.

Key words were:
AS OFTEN were the key words. But lets remember back to when we first got our cars and had the 2.73 or 3.15 gears.
Here I though I had a sports car and I could not get it to spin those tires for anything. I made the proper adjustments in TC and Gears and bingo - I got what I thought I bought in the first place. Also I wanted to get rid of the EMT's so I put down a lot of rubber and enjoyed every minute of it.
Now fresh off new tires - I am more selective as to when I spend my rubber. But I still can be real quick by playing just under the "spin" threshold and actually end up quicker when I do not spin.
Oh the fredom to have the choice - to spin or not - such hard decisions.

I will have a low mileage (14.5k) 3.42 diff for sale (possibly) soon. I am putting 4.10's in my MN6 and the installation is scheduled for 10/11. If I am happy with the 4.10s and feel i will no longer need the stocker it will likely be put up for sale in the forum. Any early interest? I also have another 3.42 diff I was going to use as a core but one of the cooling fins has broken off (according to the place that provided my new diff, I haven't had a chance to look at it yet) also I am unsure of the mileage of that unit but if there is any interest on either of these let me know.
