What to get? 3.73LSD or 4.10LSD?

Hey guys,

Am debating on what type of diff I should get. I know a lot of you guys know quite a bit about differentials. Could someone enlighten me as to the pros and cons of a 3.73LSD and a 4.10LSD.

I have an 87' 325is w/chip.
1. With a 4.10LSD, what will my new top speed be?
2. How much better acceleration will I get compared to the 3.73?
3. What would the 3.73's new top speed be

any other info would be helpful for my decision as well.

Thanks in advance,

4.10lsd.. top speed is like 200...

You could always average them out and get a 3.91lsd!
