hmm i was under the impression that ATTS and LSD's are 2 different things, though the results might be similar...

LSD's are not offered on stock ludes, they were put on some ludes in japan i believe. If you go to the prelude vs. eclipse thread, 4thgen & ludeboom are currently talking about what it takes to get LSD on a lude. (basically H22-->H22a1 trannyswap)

i don't know much about ATTS, cept that it is computer aided torque transfer.
