so, by the same token, if the difference between 3.31 and 3.55 is not much, does that mean the difference between 3.55 and 3.73 isnt that much? I ask because the car I was originally getting had 3.73's in it, but now I "might" get one that has 3.55's in it. I'm just wondering what kind of performance (acceleration) reduction i'm going to get by getting the 3.55's instead.
That's enough to notice, but not all that much in terms of hard numbers unless you're racing. Let's say your car with 3.73's can do a 30 - 60 mph sprint in second gear in 3.2 seconds. With 3.55's, plan on the same sprint taking 3.36 seconds. You'd never be able to notice 1/6 second without a stopwatch.
Heads-up from a 30 mph 2nd gear roll, the car with 3.55's will be about 2/3 of a car length back when the car with 3.73's hits 60 mph. By direct comparison, it'd be obvious. Without it, well, people claim all sorts of wild "improvements" that don't hold water.
For the change from 3.31 to 3.55, the correction is about 7%, or you'd be improving from about 3.58 seconds to 3.36 in that same little sprint. About a car length in the 30 - 60. Still need a stopwatch for the time difference.

3:31 6000 in 2th = 73 MPH
3:55 6000 in 2th = 68 MPH
4:10 6000 in 2th = 59 MPH
3:31 6000 in 4th = 147 MPH
3:55 6000 in 4th = 137 MPH
4:10 6000 in 4th = 118 MPH
3:55 6000 in 2th = 68 MPH
4:10 6000 in 2th = 59 MPH
3:31 6000 in 4th = 147 MPH
3:55 6000 in 4th = 137 MPH
4:10 6000 in 4th = 118 MPH
About 5% less.

and don't forget you will have a torque multiplication issue the lower you go with the gear ratio(Higher numerically) in wheelspin.. It will be harder to launch hard with stock tires with 4.10's when your used to 3.31's
