Gear for rear end - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

a6pk2go · 10-24-2008, 12:01 AM

Does anyone know if they will be offering a 373 rear end gear? Myself I think it is a really good road gear. My brother used to have a 488 in his Chevelle and it would be cranking some serious RPM's going about 55 mph. That would be good on the low end but I want a gear that will do good on both ends. I have search this forum and I hope it can come in something besides the airplane gear I saw earlier.

they will be offering 3.73's in the second model year.

Thanks Headpunter

Do you know the rear gear that is going to be in the 2010?

For those of us that wanna swap the gears out on the 2010 car for 3.73;s, what would be a good brand to buy?

Dom · 10-28-2008, 07:48 PM

Why do you guys want gears already? A6 is geared much higher then A4. You might end up over gearing.

10redrocket · 10-28-2008, 08:10 PM

A6 Ratios:
first 4:03
second 2:36
third 1:53
fourth 1:15
fifth 0:85
sixth 0:67

Rear 3:27

You can do the math to figure RPM and how it changes for different rear gears.

ZZcamaro · 10-28-2008, 08:38 PM

If somebody wanted to swap...What would they want to look for? Would it be the same gears as a corvette? maybe a GTO? I don't think I will change gears as I am going to build a high horsepower forced induction car, and too high of rpms on th ehighway will be BAD!!!! But I know that is what some people reading this thread want to know.

I'm going to assume you're thinking staightline racing -

Well, if you go too short in the rear, with a lot of power, you could be just wasting a lot of time spinning your tires unless you have a great set of meats and your suspension is dialed-in. Off the line, unless you can get good enough weight transfer, all that gear is going to be more harmful than good. I know there are gear calculators out there, so it'd be nice to see what tranny gear would be optimal to match the rear gear to, so depending on if you're running an 1/8th mile, or the 1320, you could set your car up to be in the powerband as you go through the line. I think GMHTP was running their stock G8 GT through the traps just after shifting into 4th gear, so maybe 4.30s would get you close. I think, depending on your tranny, and subsequent engine, you're going to have to consider redline and fuel shut-off too because it won't do any good to expect to run your L99 to 6500 RPMs when it redlines at 6000 (I don't recall if that's the correct redline..) More-or-less, you should probably put together a plan on what you plan on running, power-wise, get an idea of your powerband, and then calculate the gear you'll be in going through the traps, and adjust your ring and pinion to that number.
