I've changed my rear diff to the 3.9 gearset from the 4.08 and hopefully this will make the 1'st and 2'nd shifting easier, SRM and less rev limiter bounces.

Time will tell.

I've been driving with the 3.9 gearset for a few miles now and found the difference between the 3.9 and 4.08 driveability much better. The SRM performs flawlessly and no real differences in rev matching. The acceleration is more linear with no bouncing off the rev limiter anymore.
I've noticed that normal street driving is now more in 4'th gear; 80 Km/h @ 3000 RPM; 60 km/h @ 2500 RPM; instead of using 5'th gear for street cruising. 120 km/h is 3000 RPM in 6'th gear and instant passing acceleration, when you need it. I am much more content with the 3.9 gearset, versus the 4.08's.

Just my 2 cents
