What gears to go with?

[03Glock]

Its a 06 auto GT with 3.31's right now. I was thinking 3.73's or 4.10's. I am thinking about getting the 3.73's for when I boost or spray it. What do you guys think.

 

[cobra_4]

On boost or the bottle I'd probably go 3:73's.

f/i other than turbo id go 4.10's if going turbo id go 3.73's

4.10s. It's a lot easier/cheaper to play around with taller/shorter tires if you need to.

 

[Hitman]

4.10

 

[Haze28]

4.10's!!!! I woulda been depressed if I went with 3.73's in my car. The 4.10's made the car twice as fun!

 

[08StangGT_CS]

I went with 3.73s. Go with 4.10s

 

[Hawgman]

4.30s




Only because everyone else said 4.10s

 

[stkjock]

4.30s




Only because everyone else said 4.10s

why not 4.88s!


OP - 4.10s as said, you can use a different size tire to make adjustments.

can you even feel the difference between 3.73's and 3.31's? Ive never been in an s197 Auto with 3.73s.

+1..^^

I want to go 4.10's, but with the tire sizes I'm looking at, going 70mph the rpms would be at 2500-2600.

sure can, I dropped down from 4.10's to the 3.73's. Gave me a hell of a lot more room for highway runs over the 4.10's and I still got 1.9 60fts on STREET tires.

I know if you have a tune from bamachips, Doug will adjust your tune for your gears and tire size, to wear your tire size doesn't play a factor, but everything is correct. For example I have 4.10s and my tires are 245/45/17 which are about 25.7". At 70 MPH my RPMS are just under 2500 and at 80 just under 3000. My speed odometer is correct.

 

[Hitman]

4.56 + 28" tire + 175 shot = FAST!

 

[Haze28]

4.56 + 28" tire + 175 shot = FAST!

Hell yeah!!!

if you go turbo i would keep the 3.31's. I have 3.55's in my car running a turbo.

 

[Freaknazty]

yea i went with 3.90's before the turbo went in and im seriously thinking of throwing my 3.55's back in

 

[gmantheman]

I always thought with a turbo or centri you would want a steeper gear to get the RPMs up to boost level.

 

[Dex]

steeper? You mean higher? You want a load on your turbo so putting a higher gear in (3.55's) will help the turbo spool.
