Need some help from the forum pros.

1. When searching for lsd's and five lug parts, do five lugs automatically mean lsd?
2. If no, what is the best way to check?
3. If I want to install a Quaife ATB Diff, will I need to start with an oem lsd or can I use the non lsd diff and add the Quaife?

Thanks Troops.

i think it all depends on the lsd part. some offer lsd's for 240's that came with it and some offer them for one's without it. I know nismo does this, they have both options available. The way to check is to jack the car up. look on your pumpkin and there should be a sticker on there. Orange sticker i believe. But that may have fallen off over time. If the car is an SE it has lsd. Or you could always jack the car up and turn the back wheels and see if they both spin in the same direction.

Quaife is crap.
