Does anybody have stats on what improvement to acceleration etc this would give? Does a 15% mean 0-60 improvement by 15% as this would equate to about a second off the quotes figures.

On standard gears you can hit 60mph in 2nd gear but with the lower gear you will need an extra gear change as you wont hit 60mph till 3rd.
(However the 0-100kmh will be slightly quicker as you need 3rd gear to hit that on standard gearing)
The links I posted above contain some useful graphs for acceleration with the different drives.
This is also very interesting reading (assuming the website the data was garnered from is correct) http://vlsicad.ucsd....i/perf_est.html (does not work in Chrome).

I've just used the same thing to get the 4.625 numbers, but it is spitting out completely different results - did you change anything from Stock apart from the final drive?

i.e
4.1 x 1.16 = 4.756
4.44 x 1.16 = 5.1504
4.57 x 1.16 = 5.3012
4.625 x 1.16 = 5.365
Here are my numbers:

I'm off to look at the pretty graphs now

Other than worse economy and more noise ..... there doesn't seem much benefit to changing!
