    Even Techno Pro Spirit website only states 4.5,

    I wonder wat it really is then.

    Cheers

    Its a 4.5, not a 4.556. The 4.556 is a TRD or another part.

    wicked through the gears but utterly useless for long drives
    should go through the gears like a dirt bike

    will be a pain in the arse.. even for track work, because you will be changing gears so much and get stuck in wrong gear more often... might be good for rallycross or hillclimb, but on an open track... pain in the arse...
    you might be better off getting the gearbox ratios sorted to your powerband first.. and then worry about diff later.
    from someone who owns a 4.5 in an ae86 i can tell you its not that much different for gear selection. up down and flat tracks pose no issue.

    with the setup i am running, my powerband is 5000-7000 rpm so the 4.5 keeps me up there with the rpm's nicely

    also it befefits in acceleration quite a lot and long drives it sits around 4000rpm in 5th
    no biggy really. you get used to it.
