    3.7 is the lowest

    but if it's for drifting wouldn't you want that quicker acceleration

    Just swap the diff. Gearboxes take longer to change, can't help if we don't know what set you are running (Gearbox?).

    it helps if you search mate.

    Theres plenty of info on here and elsewhere bout the info you need, hell i even wrote an article on diffs.

    good luck finding a lower diff ratios for the borg tho, but methinks you should already have a 3.9 in the borg????

    KE70 with K40 has 3.9 ratio. KE70 with K50 has 4.3 ratio. Auto have 4.111. Borgwaner diffs

    TE72 most TE72's are 3.727 T-series, some very later models are 4.1.

    AE86 S-series are 3.9 S-series.
