its stock for now but wheel bearings are going but i have a rear end with 4;10 sitting in my shed so i was going to put that in i know 3:73 would be better for the a4 but anyways what you guys think . my first mods are going to be a stall. and cam. of course thats after the exhaust and intake and a couple of other small things.

IMO 4.10's are too much for an A4 unless its a race car.

Is it a daily driver?

too much. get 373s if anything, my 323's cruise around 1400rpms at 50 mph

Depends on what you plan on doing with the car. For a weekend cruiser or daily driver with a short commute wouldn't be too bad. If you have a long commute you won't like them.

Problem that i hear with 410's in an A4 is if you get your car you will run outa gear and have to use overdrive before you finish the 1/4 and it will actually hurt your time more then it will help

It doesn't hurt your times. I ran all last season on 4.11 gears with a stalled and sprayed A4. Best run was an 11.36 @ 119. Look for those gears to shave .1-.2 seconds off of your 1/4 times alone.

Yeah...I love the 4.10s in my car. They knocked me down to 12.30 just with those and headers.(and stupid little stuff).

It depends how much power your gonna be making, what size tire your gonna run, and how high your gonna spin it. Fill in those blanks and I can give you a good answer. If your not gonna run it at the track, then no, I would def not go with 4.10s in an auto.

It all depends on what your plans are for the car. What tire size are you running and do you drive on the street mostly or are you looking to track the car?

The OEM rearend(GU5-3.23s')developed a 'growl' in Oct. 2004 on the way to SLP day in Englishlish,N.J. Being that I'm familiar with rearends,I wasn't overly concerned.I have 3 complete rearends in the garage and many gearsets hanging on the wall and many carriers sitting on the shelf.Since the 'hypertech' would accomodate a 4.56 thru its' programming,why not put the 'ultimate' gear in.The original OEM rearend is just being rebuilt with its' original 3.23s.It had a deteriorated right side carrier bearing.
Now 1st and 2nd are 'interesting' and so is kicking the throttle at 75mph.
I'm spinning 2400rpm at 60mph and 3000rpm at 75mph,not as bad/high as I thought they were going to be.
My 25.5 mpg with the 3.23s' has now become 20.5 mpg(theoretically it should have been 18 mpg based on mechanical ratio change) with the 4.56s'.
The engine is stock(305 hp) and it's been consistent 13.70s',the 4.56s' have made it consistent 13.20s'. 1/2 sec. ET gain with the gear change.

i had 4.10s in my 95 z28 and it was a daily driver. i picked it up in florida and drove it to oklahoma. thats a 25 hour drive. i drove 6 hours one day. then 19 hrs straight the next. i got around 19 mpgs on the highway the whole way. along with the 4.10s it had a 3500 stall, long tubes, cai, shift kit, tranny cooler, and a tune. ran 12.70s. go with 4.10s its not as bad as everyone says.
