Which final drive for auto to manual swap

[95RedBMWe36M50]

I'm in the midst of an auto to ZF manual swap for my '95 e36 M50. Trying to decide which final drive to put in as the current drive is a 4.10 which I believe is to high. I'm building the car to be a fast and quick street car to autocross with. Desire quick acceleration and good top end, say 140 to 150 mph. I'm doing the suspension, breaks, wheels and tires now, will supercharge this engine until it blows then do a S52 swap. Any and all advice would be greatly appreciated. BTW - yes, I did do a search and didn't find any threads that discussed this topic.

with FI those would be a wise choice, but if it was staying NA i would say go 3.73
