I have a few questions that are altering my choice of what options to get on an A6 LS3 08 Coupe.


1)What order is the list of fastest to slowest 0-60 with a z51 A6 , an A6 2.73 gears only, and a stock A6?
2) What 0-60 time (4.3,4.4 etc.)am I looking at also for each option listed above?

I am guessing the 2.56 to 2.73 would not really change anything, but maybe the z51 package stiffness will help my 0-60? I am so confused!!
All help is appreciated
Thanks

 

I'm gonna assume you need a quick 0-60 so you don't get hit from behind on a freeway onramp.

The 2.73 gear is pretty much a given for quicker acceleration, so you can eliminate the standard 2.56 from your chioces.

A option to consider would be the F-55 which includes the better brakes. On freeway onramps and everyday streets, keeping the tires on the pavement is a good thing and the F-55 does it better (IMO) than the Z-51.

So you had three choices and now one is gone, but another popped up. The math says, Oh Gosh, it's still three.

Try test drives at the dealer. Then enjoy your new Vette.

 

Atleast I know one option is gone Now this just means I have 3 better options to choose from. Thanks for the information HOXXOH, I will mostly be doing city driving during fall ,and spring, but I would be doing lots of highway driving to car shows in the summer.

Now it comes down to a new question of; is the 2.73 alone slower than the z51 package that includes the 2.73 ratio, from 0-60? ^ ^
The thread lives on!

 

Back up a second, if you're not going to race the car, your butt might not even be able to tell the difference in acceleration on the street. But you might be able to feel the difference at the pump if you're doing a "lot of highway driving". The 2.73 will probably cost you more fuel in the long run.

So what's more important to YOU? Economy or bragging rights? Neither answer is wrong. Sorry to put you back in the same boat as before.

 

The heavier rotors of the z51 package and the additional weight of the larger calipers will slow your 0-60 down. Also 1LT will be fastest. LOL

 

Looks like I am very close to buying a Black on Black 1LT C6 A6 (GU2 2.73) . Cheap, fast and light. Thanks for the help.
Bragging rights over economy is the way I see it
Save the wave!

 

The best part is.... You can't go wrong!

Hope everything falls into place for you.

 

Thread summary:
List of fastest 0-60 is
1)A6 GU2 less weight than a z51
2)A6 Z51 more weight than a 1lt
3)A6 Stock gears make the car a slight bit slower

Now I am a lot closer to buying a GU2 1lt coupe A6
Enjoy your rides guys
Save the wave!

 

I have an '08 coupe, F55, 2.73 axle, 3LT and I am very happy with the package. I don't think the performance difference between a 1LT and a 3LT package is measurable, all else being equal. I can't believe the difference in weight between the standard brakes and the brakes that come with a Z51 or F55 equipped car is all that much and could also make a measurable performance difference. JMHO.

 

Let's see if we can make it more confusing by adding that the Z51 package includes sticker (softer compound) tires for additional traction and the F55 package has selectable ride choices including a sport setting that's designed to keep the tires in contact with the road for additional traction.

Have you considered the M6 as opposed to the A6?

My guess is that unless you are an excellent driver, no matter what combination you get, an excellent driver will be able to beat your 0-60 time with any other combination.

I'd suggest you buy what makes you happy and learn to tame the beast. There's not enough difference to fret over.

 

I know all about the physics of it : ) The Kinetic force, F=ma , springs force etc. It would take years for me to figure it out for maybe a .015 second difference without any driver error. I was just trying to see if there were any real proven results out there. I live in New York, so a manual is out of the question sadly. If I move anytime soon to a less crowded state I will definatly get a Manual 6
I am still deciding on wether to get the z51 package vs just the gears it's a $1,000 give or take price difference in a nutshell, and I live where there is a pot hole at every other 15 feet literally. I hear rumors that the z51 is too stiff for "crappy" road driving, so I am going to say that the F55 option would be nice. I am not sure if I am ready to spend the money on it even thought it is a Brilliant system designed for the corvette.
I still have 2 months and a few weeks to decide so I will see and post my final answer when I order or find a used one for the right price. Where I live a 70 horsepower car is all I need sadly due to traffic and lights, but I would not mind having a vette that can get me that rush once in a while!

My current American car has some giddy up to it, but I want something pretty fast, and I want a car that comes with the bragging rights of a true american v8. If finding the right option is this hard, I can only imagine how hard it must be to try and name a child

 

That is the car I'd be buying if I were to get another new C6.




Many people will try to refute that 'bumpy roads/Z51 stiffness' issue but I do agree. On these rough NJ roads that Z51 suspension shakes the car and much of the handling/cornering gains are almost totally erased by a car that's now skittering and jouncing around on potholed roads, my base suspension car stays planted and soaks that stuff up with better compliance.
F55 is an awesome compromise as well.

 

If I were buying a car for drag racing purposes, I'd buy a base suspension. The softer springs will help weight transfer. I had two C5's. One had base, one had Z51. I always got better 60' time on the base suspension car. The cars were identical other than that (well, one was a convertible, but that's only a 20# difference).

 

I won't lie weather its auto or manual the car is stil F***ing fast lol

 

That is, without any denial nor doubt whatsoever, the truth.

 

Well now we're off the original topic completely. First you wanted irrefutable 0-60 times with no room for opinions. You were also concerned about highway miles. Now we're talking pot holes and light to light in NY!

You need to forget about all that 0-60 talk because THAT choice may not be your best solution.

Using the new data... you do NOT want the Z51 because YOUR streets were not made for it. Face it now or regret it later when your azz is crying from all the punishment. The base or F55 will be MUCH smoother in your neck of the woods.

And now that we know you literally meant "0-60" because there's no room left in town to go 66mph, there is only one solution to give you the SLIGHTEST edge, and that's the 2.73 gear. But believe us, there aren't any stock options that are going to overcome driving ability on the street. You're talking perhaps a tenth of a second difference in 0-60 times with a professional driver on a test strip trying over and over. There aint no cop in town going to let you practice till you get it right.

My advice is to buy the options that are going to make you the most COMFORTABLE. Meaning physical & financial comfort. I am not convinced you are going to be able to drive the wheels off ANY model where you live. Please believe me, I live outside of Philly. This is my second Z51 and I really think it'll be my last. There just aren't enough clear roads to appreciate it and it doesn't help my drag racing. I bought it because I THOUGHT the additional trans cooler would help... It doesn't. I had to add a B&M to make a difference.

Maybe it's just me, but I'd be going for creature comforts since we're talking a daily driver instead of a race car for you. They're ALL going to be faster than 99.99% of the cars that pull up next to you. So why not be comfortable while you're waiting for them to catch up at the next light?

Sorry this is so long, but these decisions get very expensive later. Opinions are less than free here. Take them for what they're worth.

 

I agree with you 100% on the whole 35 MPH limits everywhere : )
I think I am going to just stay cheap with the 1LT coupe automatic, NPP , 2.73 for a better feeling in my head not my pocket, and I will see about getting aftermarket shocks later on to improve daily driving comfort.
Thanks for your help guys it made my pick an easy,comfortable, and a financially sound one.
Save the wave

 

For what it's worth, I think you're heading down the right path now... and that coming from someone who has none of those options. Nice choice. And don't rule out the 2LT or 3LT if you like anything in those packs. Just know the premiums are high for very little added value.
