Seems like it's a motorsports LSD. I don't think I would like to give up so much streetablity/low speed driveability. Carbon 1.5 way could be worth a try, or at least the pro model which allows for adjusting preload.
So with your GT LSD were you able to maintain ABS? I was under the impression none of these support ABS? I think I would give up ABS for a good smooth LSD.
Correct me if I am wrong, it is not possible to use factory stub shafts (with ABS ring)?
