    Yeah don't forget that the LSD was an option so its most likely a disk to disk with open centre.

    As mentioned before, i have a 4.3 which accelerates better, but on the freeway at about 110-120 it sits around 4 grand. If you go for 4.7 up, your freeway cruising will be revving pretty hard, not good for long trips.

    4.1 would probably be the best compromise for street

    well just a question I always think about, as my car the diff has been replaced with a t series unit since I bought it, I wonder if my speedo reads incorrectly coz the final ratio is now different from stock.

    yeah most likely you would've had a 3.9:1 ratio in your S series diff, and now with a T series there could be a chance you'd even have a 3.7 or 4.1 or 4.3 now
