Any 1/4 mile times to compare the two ratio's? Have had a problem trying to order the 3.15s. Should I wait or order it with the 2.73s ? Am not a big 1/4 miler, but enjoy a blast to the hills. Sold the 92 6sp so going to an A4 will be a big change

Thanks

:) :)

 

2.73's are a slouch......order 3.15 optional ratio, or better yet, have a 3.42 or 3.73 installed upon getting the car.

 

Get the 3.15's do not waste your money on the 2.73's.Later if you don't want to go to 3.42's,you can add a TC to the 3.15's and you'll have a boatload of FUN thru the hills.Either with the 3.42's or 3.15's add the TC.

Don't waste time with 3.15s buy the car with 2.73s and then install 3.42s. You can buy a good used set on the C5 Parts For sale Forum for $500.00.

 

A4....You need 373's! :hurray: :hurray: :hurray:

 

I'm sure I'm just in denial here :lol:, but one good tihng about the 2.73's is that you don't have many traction problems!

I've been telling myself that I need to upgrade gears/TC also, but any of those upgrades will result in traction issues. What good is power if you can't plant it?

So, then you're looking at different tires, possibly wheels, which cost more than your gear mod.

Ask yourself - how fast are you gonna go through those twisties? And can those speeds be accomplished by using gears 1 & 2?

Think twice - blow money once. :D

 

Without question you are in denial :D . My car came from the factory with 3.15s and I did not have traction problems. In fact unless I brake stalled it I couldn't spin the rear wheels. But since I modded my car I have no problem spinning them now :yesnod: .

I can attest that the 3.42 with stock TC.... is a no brainer. Just mash the pedal down WITHOUT THOUGHT. You will get some tire squeal... but far from it being a traction "problem".

Maybe with the 3.73 with a higher stall TC you may have to think a little on a launch... but that would be the only instance.

Agreed; that with the more radical 3.90 or 4.10 you WILL have traction issues. running stock tires.

there should be no issues with ordering the G92 3.15 from the factory. Is your dealer telling you they are on "constraint" ?
If so, there is no worry. AlGore has forbid all A4's from coming with the 3.15; so the G92 is ALWAYS on constraint since they all can't be built that way. But this "constraint" has never (as far as I've heard) actually delayed the building of a car.

If I were you, I'd hold out for the 3.15's. Try another dealer or call one of the sponsor dealers and find out if there is a problem. I've had both in my 02, and I like the 3.15 much better if you like to feel it SOTP. About 0.3-0.4 difference in 1/4 mile, which is 3-4 car lenghts. The only downside is the tires spin much easier... :thumbs:

 

JUSTCRZN, I have the 3.15's and they are worth waiting for. Did you order the Z51 suspension? Z51 requires 3.15 axle ratio with the A4, so they may send the order thru before an order for just A4 and 3.15. 3.15 is usually on constraint at the assembly plant, I believe due to CAFE restrictions. Congrats in advance on the new Vette. :cheers:

 

If those are the options the 3.15's are a no brainer. When you get the car have the 3.15 casing upgraded to 3.73's gears..Now you will enjoy the car!! :yesnod:

 

:iagree: THE 3.15'S WILL KEEP A SMILE ON YOUR FACE :) THE 2.73'S
SHOULD NOT BE AN OPTION. THE OFFER SHOULD BE 3.15 OR 3.42!
GOOD LUCK & ENJOY. :party:

 

Don't waste your time upgrading to 3.15's. Get the car with 2.73's. Take the additional money and purchase 3.42's or 3.73's. If you aren't going to be at the track often. . .go with 3.42's.

As stated earlier 2.73's shouldn't even be an option. . .3.15's aren't worth the money.

My .02 cents worth. :cheers:

 

OK, I know I'm going to incur the wrath of 90% of forum members by defending the 2.73, but I must point out that Chevrolet's data (NCM website) has the following 0-60 times for 2001 models:

A4 2.73 4.90
A4 3.15 4.75
M6 3.42 4.60

Obviously, the 3.15s are better and I know the STOP meter will be better as well, but 0.15 ain't a whole lot. And "2.73s shouldn't even be an option" . . . come on!! I've never been a car that pulls so hard in 1st gear as my 2.73-equipped '01 coupe. I know it would be even better with lower gears, but it's pretty awesome as is. If any of you guys with the 3.42s are ever in Chapel Hill or Albemarle or Charlotte (will be moving there for a job soon), take me for a ride - I want to see just how quick it can be.

Also, on a 100 mile trip between Albemarle NC and Chapel Hill NC, I routinely AVERAGE 30 MPG and have an all-time high of 33!!! Pretty impressive given the performance of this car!!

Well, that's my $.02 . . . bring on the flames . . .

 

In the 5 Corvettes I've owned, I've never worried about rating their MPG :)
Although I agree it is impressive.

I have driven A4 C5's with 2.73, 3.15, and 3.42... all with stock TC.
All I can say is drive each one yourself. If you can't tell a difference, then I agree; save your money.


But, boy... I sure could tell a difference. And I might point out you are not wasting money with the G92 3.15 factory option. The 2.73's are worthless, but the G92 has the case that can accept the other ratios, or is worth what you paid for it if you swap out the entire carrier.
Even if you buy a brand new 3.42 carrier (which is what I did) and swap it for your 3.15 carrier... AND get no more money selling your 3.15 other than what is cost as an option; what you do get is free usage and the fun that goes along with it during the time the car is kept all original.

One other thing to consider is that going from the 3.15 to the 3.42 in a A4 requires no reprograming. period The factory 3.15 program has enough lee-way that it can handle the 3.42
But, going from the 2.73 to the 3.42 will require a reprog... which will cost as much or more that if you purchased the G92 option in the first place.
The 3.15 in a new A4 is a no-brainer. It's a win-win deal.
And don't let the "constraint" place fear with any delays. The G92 is on constraint at the get-go; from the very beginning of each model years run. But like I posted earlier, I have never heard of it actually delaying the building of a C5 by even one day.

Thanks for all of the coments. We will hold out for the 3.15s. The constraints have been inplace since early Dec. The dealer is hoping we can get the car ordered in late Feb.

Thanks again :flag

 

JUSTCRZN

does your dealer have an available allocation?

They may not, and are using the 3.15 constraint as a ploy to hide the fact from you.

 

Get the 3.15s. They're around 15 per cent lower geared than the 2.73s. The 3.42s are only another 6 per cent or so lower than the 3.15s. Besides, who wants to put a brand new car under the knife to put a new diff in it? You will enjoy the 3.15s, trust me, unless you're just buying the car to drag race it.

Agree the 2.73s are a joke, inspired by EPA. :D

 

in Spocks voice: 8.6% to be exact :)

 

I stand corrected! :blueangel: Actually, 8.57142857142857142857...% :lol:
