My M3 (e46) Getrag tranny and the Z4M ZF tranny aren't geared all that different and I think the final ratios are pretty close as well. The gearing up top is perfect but the gearing down in 1st/2nd is way to aggressive..

Changing the final drive would probably net you better results in 1st and 2nd but you'd be sacraficing 3rd-6th.. the ultimate thing would be to find out a way to gear 1st and 2nd to be a bit longer.. especially 1st.. M cars have always had a notoriously low first gear.. which creates the impression that the car is quickier then it really is.. soon as you add F/I that 1st gear is absolutely worthless.
