Hey guys, i was just wondering what gears u guys have or had when your car was stock, mine is an 02 and my time is in my sig that i ran at MIR, i was thinking that that was a pretty good time for nearly a stock vert and im not to clear how to read those RPO codes that everyone keeps talking about!

Just check the rpo codes(numbers) on yourdriver side door.Look at all of them till you find either GU2(2.73) or GU5 93.23)It should be somewhere mid top Just see every code.If you have the GU2 that is a good time.

it says GU5, what does this mean?

it means the gears on your rear are 3.23... and it also means you get bad gas milage like me :D

So what gear set up is better, and why?

Most of the A4's had the 2.73s...but some I believe came with the 3.23s...but I don't think they're as common. The M6's like mine are 3.42's.
It's all relative really. Because mine is a manual, they give me an extra overdrive than the auto...thus helping me out with my gas mileage. An auto's 1st gear is going to redline at say 50mph while the manual's 1st gear is going to have a little more get up and go but will redline at say 43mph. At higher speeds, the higher geared cars (2.73 or 3.23) are going to have more speed thus faster. Of course, it really depends on what kind of rwhp you're putting down!!

Thanks for the info. I have the 3.23s in an A4 SS vert. I don't know if this is uncommon or not.

All automatic SS/WS6/Hawks were 3.23's.
All normal Z28's, Formula's, and TA's, were base 2.73's with an option for 3.23's. Unfortunately that option was not checked nearly as often as it should be, and many of the normal cars are saddled with 2.73's.
In reality 3.23's are good for about 0.1-0.2 tenths in the quarter, and they make the cars feel much livelier around town.
But 2.73's are a great highway gear. Grabbing 2nd for a 70-95mph WOT rush on the highway is pretty nice.
I have 2.73's and so long as I'm traction limited, I have no problem with them. The higher gears are a pretty big advantage when you start doing traction upgrades, though.

Thanks Todddchi. That's was what I was looking for. That explains why this car cuts loose easier than my 02 Z28 did.
