any of you guys running 410 gears in an a4 car and if so is this to much gear for an a4 ,no stall yet , problems Im worried about are traction ,and tranny ,would 323s be a better choice I have both ?

 

What is your purpose of using the car for? If you do more daily driving and hwy/fwy traveling I would stay away from 4.10's and go with 3.73. 3.73's are a all around good gear for the A4. I love mine.

 

I have 4.10s in mine. If it was anything other than a "racecar" to me i would change them out.

 

A friend of mine had that setup in his Z28 for a few years during high school and it was daily driven. He loved it and it made it so much more fun to drive...even over my car with an A4 and 3.73s.

 

I would personally prefer 3.73's for daily drivability, but to each is one's own and that is your call man. I would personally throw some Drag Radials and a Yank SS or Vigilante, but thats just me

 

go with the 3:73s man...the 4:10s will take your rpms too high to want to drive that thing on the street....the 3:73s will allow you to run good times and still get good mileage on the streets....3:73s are the prefered gear for both man

 

what series would I need for a 94 ta a4 ?

 

You could always split the diff and go 3:90.

I personally think 4:10 are way too much for an auto car. I would probably o 3:55 if I had an auto, 3:73 at the very lowest.

what about for a 6spd car ?

 

My 6 speed has 4:10's

I think they help out a 6 speed a lot but there again it depends on your total setup.

You auto guys can run a stall and get rpms out of the hole that us M6 guys can't, so we can go lower gears and get ours closer together and still have the topend of the super deep 50% over 6th gear.

I'm by no means an auto expert, I would stick with what has worked for other guys. I think a 3600 yank and a set of 3:73's would do awesome at the track for you and still be pretty streetable.

 

Depends on how much power your making! When I was just bolt on's 410's were awesome but with a 100 dry shot I was shifting into overdrive before the qurter mile so I put 342's in it and couldnt be happier.

 

i have 3.42s behind my a4...and i still feel like im turnin to many rpms on the hwy....tho i did go up from 2.73s....so i was used to 2k rpms at 82mph

 

maybe some 60 foot times to go with the gears, and highway rpms
I'm running 1.75-1.73's with a 2800 9.5 vig and 342's. Stock long block and bolt ons. No bottle, highway i run 80-85 at about 2700-2800

 

As mentioned above, depending what the car is for. A 3.73 gear would be great for all around street as well as track oriented car. I run a 4.10 gear on my set up. More of a track car and it rolls on 28" tires.

 

I run 3.73's which is IMO the best compromise for a car that sees the track and gets driven alot on the street. The 3.73's are even more than I prefer on the highway so I cant imagine what 4.10's would be like. I use to daily drive an hour each way to school with my 3.73's and a Yank SS3600 Stall and that was a real fun combo that performed amazing at the track and was still comfortable on the street.

 

My '95 Z28 came with the A4 and 2.73:1, I thought the 3,73:1 gears I installed were perfect. I wouldn't want first to be any lower, nor OD. 4.10:1? Never!

 

It's only another 10% going from 3.73 to 4.10. If I had it to do again, I wouldn't do anything but 4.10s in my A4. But you also don't want to shift into 4th at the track.
