I was referring to the gearing at the track.
You need to do some calculations to determine the suitability of the different final drives.
For example on the M the stock diff is 3.62, with 3.91 and 4.10 as options.
I looked at the speed/rpm through the various corners and the fact I was hitting the rev limiter up the back straight in 4th gear.
In my case the 4.10 was an easy decision after looking at the data.
