Speed v Gears

[shimmy]

has anybody got the graph/table that shows the comparisons of gear v speed for both stock diff and 4.10 diff?

You can grab one here:

Not sure if that is the one you are looking for but it should help as you can alter all the info to make it e46 m3 specific.

Shimmy !! ... I want one of those 4.10 diffs please mate !!
Using that calculator from phat, it works out that my car will do 243mph in top ! ....

that Excel programme isnt too difficult to use first time round is it ?

lol @ being geared for 243 - perhaps revving that high might explain your crank situation

Buyer beware, the info in the above is ONLY for cars imported into the US ... did they alter them ? You could manually input the info for UK spec cars and the calculator would still work i think

Here is one filled in with the data for the CSL attached, I found the gear ratios here:

Only 6th gear is different to the site that Duncan posted up.

Dunc the only way your car is going to reach 243mh is if I push it off the ramp and over a cliff!
