LoL

Here is a simplified explanation;

Lets assume we are in 4th gear with an M6 (1 engine rev for 1 trans output rev - 1:1). Then you get to your rear end gears which are 3.45s (I think), so one rotation of your transmission gives you 3.45 revs for your axles... and then your tires diameter add to the equation... well if you change the rear end to 4.10, you are getting almost another rev for your axles... so going back up the drivetrain, you end up having more revs of your engine for the same revs of your tires, thus more fuel consumption. But the benefit is it requires less engine power to get those wheels rotating at the same rate as the old 3.45's, so in effect makes you accelerate quicker, and shorter 0-60 times with the same engine power.

I guess the bad thing would be is if you already have a hard time keeping your wheels from spinning, the shorter gears will make it worse.

Feel free to clarify more folks.

Ah, 3.45 turns of the driveshaft gives you 1 turn of the rear axle....

With factory gears your car goes this far with (engine) 1000rpm's
[--------------------------------------------------]
with 4.10's it goes this far with 1000rpm's
[----------------------------------------]

Duh, thanks guys

how much will 4.10's lower your top speed? how much will 3.73 lower it?

Try these calculators... I have heard of a guy that took his 2010 over 150 mph.. procharged, and could not get anything out of his sixth gear... so I would say a shorter gear is going to make 6th usable for top end... if that's what your looking for..

from http://www.tbyrneperformance.com/ for $609.99

And I’m waiting for it.

HAHA

you could have gotten a much better deal with the group buy that is going on.

Wonder if we will see any 3.92 gears?

i know of a CTS-V in town that has done 184mph (stock with a tune) and they have the same auto trans gear ratio's (6L90E), and come stock with 3.70 gears

so i really would not worry about top end loss of course the cts-v has around 560hp at the crank,, but most of us here that are really modding our camaro's have that plus some.

i have the tune from his cts-v and i will be using the factory cts-v shift tables for my camaro after the 3.70 gear install

[WICKEDSS]

for that price are these gears made out of tungsten carbide?

[WongBob]

LMAO @ tungsten carbide.

If they were tungsten they would be more like 8k... we use tungsten in oilfield applications and man thats some expensive stuff.

I never knew Richmond was in Liberty, SC....I go by there everyday on my way to work. I am still trying to decide on 3.73's vs. 4.10's. I feel like 4.10's would be more expensive because I would need a set of Nitto's to keep traction.
