    They said a M3 or M5 diff may also work but they are also aluminum so Im leery of that.

    Once they put my car on the lift both guys were suprised at how small the half shafts are especially with the stock power.

    If I do this late in the summer I will also have them upgrade my trans with Viper forks etc etc etc.
    Yayuh!

    speaking of diff's I still wish someone would put a quality set of ring/pinion gears in a new style diff and see if it gets rid of the whine forever

    Re: Difference between early & late differentials

    So, if I were to sum this up then the 06' differential is stronger than the earlier 04' & 05" models but that there is an even more improved version out there now. And...although the 06' differential is somewhat stronger is is still susceptible to all the other maladies (wheelhop, clunk, cradle bushings, etc.). Have any of you guys out there grenaded an 06' differential? Anyway thanks a lot for all the replies and info. Awesome Forum!

    Re: Difference between early & late differentials

    I grenaded my '04 model into pieces with wheel hop (that didn't start until like 4k then by the time I let off...KABOOM)

    '06 models still hop, but I've had no grenadation yet (crossing fingers) and will be installing the Kars Kit when it gets warm enough to lay on my back outside. Fun Fun.

    with the old cases, they would shatter usually starting at the neck.

    Re: Difference between early & late differentials

    I have seen pics of a few of the original ones that the case shattered just behind the pinion housing.
    I don't think I have had to replace what I call the '08 style diff after I put one in.

    Exactly.

    Note the pinion gears unscathed
