Climb under the car and look at the tag on the rear end. They all should have a sticker that says the rearend ratio.
3.31 i bet
Probably a 3.73, but do what SicShelby said.
My guess is 3.73's
how do you guys think its 3,73? @ 80 mph my car read like 21-2200 rpm with 3.31's

If you know your tire size, you can find out with the RPM and gear ration in 6th.
L said above, look on the diff cover, there is a white sticker it will read 3.15 (auto), 3.31, 3.55 or 3.73
If I remember correctly: @ 75mph in 6th gear I am right at 2300rpm.
Brembo car btw; 3:73's w/19"s.
Brembo car btw; 3:73's w/19"s.
Do you have auto or stick?
why dont you just look at your window sticker, manual with no gear upgrade is 3.31 and if you have 3.55 or 3.73 it should say so.
It's a stick... and bahhh 3.31's. What do gear installs go fo these days?

$200-$250 without the cost of the gears. go 4.10s.
Are u sure?? I thougt it was more like 5hundo for my cobra? If that's the case, that aint bad at all... Anybody here have the 4.10's? The car feels super peppy as it is with the 3.30's I couldn't imagine. I wonder if that'd kill the high rev powerband which feels right about where this car shines, 4-6500?
EDIT: I chirped 2nd-4th on the way to work tonight.... Love this damn car!

What else u have done white Mach? Those are some decent times!
Put the car in your 1:1 gear ratio. Put the car on jack stands in the rear. Find a reference point on the tire. Have a friend lay under the car(on jack stands) and YOU rotate the tire exactly 1 revolution. Count how many times the driveshaft rotates per 1-tire rotation. If it's 3.31 times.....guess what? If it turns 3.73 times.........4.10 times...etc.
Thanks, I read the tag on the diff
