Gears for my setup The choice is between 3.42s and 3.73s. The car is a regularly driven Z28, A4 with 3.23s and a Yank SS4000 (I love the converter but it needs more gear behind it). "Gas mileage" is not a big factor but driveability is. I currently have a set of Motive 3.42s sitting in the garage, but I want to do this once and do it right. Feedback is appreciated.

I voted 3.73 because i have a 3.73 and 3600 vig. love it, i 60' a 1.59 on 245 nittos with this combo. A lot of the local guys around here are also running a 3.73 4000 stall setup and are mid 11's with a cam.
If you plan on heads and cam then do the 3.73 for sure, but if you want to stay internally stock then 3.42 may be better to keep you in peak tq and power range

3.73s.!
I'm running4.56s' with an A4.
Gas mileage will hardly be changed(depending on right foot).I went from 24.5 mpg with 3.23s' to 21.5 with 4.56s'.
Driveability will improve and the torque convertor will 'seem' slightly tighter going from 3.23 to 3.73 as slippage/stall is resistance dependant and gears provide a mechanical advantage over the resistance of the vehicle to get moving.

Anybody take the side of 3.42s? LOL Looking at the gear calculator in the FAQs, I really like the lower RPMs for 3rd gear and OD cruising speeds as this car actually sees very little track time.

I voted 3.73's. As stated by others the difference isn't much if you go to the 3.42's.... although I must add that I did sell my 3.42's to a friend with an A4, 382 stroker, AFR heads, big cam, stall and nitrous and he loved them.

Funny, im at the opposite end of the spectrum right now, as i am waiting to install my SS4000 stall and i have a set of 3.90s in the back right now. I went from 3.23s to 3.90s cause everyone with autos goes 3.73, so i wanted alittle edge, but if and when my rear dumps, it will be 4.10s!!!! Oh and i say dont waist the effort with those 3.42, not enough of a change for the amount of work!

I have 3.70's. 80mph is a hair under 3k. Perfect....
I would never recommend any less than 3.70's, i almost bought 3.90's, which would probably be just fine.
3.42's are a waste IMO.
