ive now been searching for the lsd now since i found out we could get one
and these are the results i can up with...
the lantis's as an option came with a "screw refuse" lsd i have never heard of this type before. but i did a search on that and all i came up with is this
"The system which restricts the differential motion of the left and right driving wheel the screw refuse coupling (the multiple disc clutches) due to function, transmits power of the engine to the road surface without wastefulness. It improves takeoff characteristic and travelling stability"
and i also found out that some type r's came with a rear strut brace
