What exactly is an LSD? and what does it mean? I am curious because I am currently looking at buying an LS integra but have aspirations of swapping a GSR into it and I'd like to put a different tranny in there as well (unless thats stupid?) and it seems like LSD keeps coming up alot in the tranny threads. Thank you for any help.
