dont mean to thread jack but i am planning on getting an hsld.
does it act like and open when one wheel is in the air. for example getting stuck on driveways?

[badbob2121]

dont have mine yet, and i dont think it should, but im glad im not the only one who had that happen with an open...lol

[S14Kouki10]

well it hastn happen to me yet. bu im getting coils soon.

but i think i read that the hsld sometimes acts like an open diff. idk

edit:
i read this
" If there's no resistance from the other gear, it will just turn. This is why, technically, a helical limited slip isn't really a limited slip. Put one wheel on ice and the other on pavement, and there won't be enough resistance to prevent all the power from going to the ice."
