I'm sure this has been beaten to death in the past but i'm new to the forum so please forgive me.

Better for everday driving?

3.73's or 4.10's?

Thanks

 

3.90s

.02

 

Keeping in mind this is a manual, 3.90's. 4.10's would make it a rocket, however you may or may not get annoyed daily driving. Personal preference, I'd go 4.10's, but that's just if it was my car.

 

I run the 3:73's.At hiway speeds you can hardly tell the difference but out of the hole, its a good thing.The throttle response is somewhat better too.

 

I liked my 4.10's a lot when I was N/A.
I still have them in the car but with the S/C 1st and 2nd gears are pretty useless even with 275/40 18's.
They're still in there since it's the proper ratio for the 1/4 mile since I go very often.

 

What do you have a manual or auto??? What year???

 

He's got a manual 06.

 

Im thinking about getting 4.10's, but i think my rpm's will be a tad too high on the highway.

 

With your tires on a stick car in 5th gear on 4.10's

60 1950 rpm
70 2300 rpm
80 2600 rpm

 

With your manual I'd go with the 4:10's. Your OD will be useable with the 4:10's. Go for them!

 

How do you know that? He has no signature. You must be physic!! Or I'm stupid... Don't answer that!!!!

Because he installed the parts and tuned the car.

 

Do a forums search; there is plenty of information and opinions out there. I have 4.10s with the manual tranny- it turns about 2600rpm at 70-75 mph. My only regret is occasionally I wish I went with 4.30s, but a blower is in my plans to 4.10s is plenty.

 

Duhhhh!!!!!!!!

 

I love my 4.10s. They work great for a normally aspirated car with a manual.

 

Just had 4.30's installed and I love them !!! The rpm's run about 2750 at 75 mph in 5th gear . I used to drive down the freeway in 4th with the 3.55's because I loved the sound of the engine at 3000 rpm's and the passing power if i needed it.

 

How much is gear install running you guys?

 

$265 parts and labor at the local mom & pop shop.

About $400 for the same job at the local speed shop...... uh, no, thank you.

 

gottcha

 

I should clarify, in my post I wasn't counting the cost of the gears- just the labor and parts needed; add the amount of the gears to the prices I posted.

And about the mom & pop shop- they've installed three sets of gears for me: in my '92 GT, my '04 Mach 1 (sold), and my '06 and not a hint of whine, vibration, etc. They had never even seen a S197 before they saw mine- goes to show that alot of the problems associated with gear whine in these cars is still indicative of an improper install.
