    FS: DiffsOnline 4-clutch 35/60 diff

    Hi folks.

    I have a DiffsOnline 35/60 ramp, 4-clutch LSD for sale.

    It's currently out of the car, but still installed on my 3.91 gears. I can quickly remove it, and have a box ready to come to you.

    It has 4 race weekends (8 days) on it, and I've changed the (recommended Motul 75/140) fluid twice.

    This is a well known, but aggressive diff - not really a dual-purpose or HPDE diff.

    New ones are $1500, I'll $800 plus shipping and PP from zip 80020.

    Selling to finance another OSGiken in a taller ratio.

    Thanks,
    --Bill

    If it’s not good for HPDE what is the best application for it?

    It's coming out of a dedicated race car.

    It's just not for the street; too aggressive.

    If you had a dedicated HPDE car it's a great choice. For a dual-purpose car, I'd get something like a Torsen, or OSGiken at twice the price

    These diffs have, and still do well on NASA GTS2/3/4 cars, and probably a group of TT cars that I'm not famliar with.

    Can you describe how this diff behaves on decel? I am curious about stepping up from a 3 clutch to 4 but have heard some mixed reviews in regards to its performance on decel. Specifically, hard under steer at corner entry.

    It has more coast lock than the OSGiken, but only by a little. It definitely is not hard understeer anywhere for me. Like I said, thinking about keeping it in my spare diff, as it's more expensive to replace.

    I just having the same LSD in all my diffs; easier as a driver to go back and forth.
