I have a 00 civic si and I am looking to put a LSD into the tranny which would you recommend? I was thinking ITR LSD but some people say that don't fit so I am thinking the JDM LSD from a CTR that would bolt right up, but which one would be better for the si tranny

 

I have an S4c tranny and have been looking for an LSD as well. Some have told me that the CTR LSD will bolt right in, w/o changing the final drive. However, my research has found that the CTR and ITR LSD's are the same, which means we will need to buy a final drive for a GSR, ITR, or CTR since the diff in the S4C is smaller and can not be reused. Can anyone confirm this?

 

Bump anyone?

 

bump. i'd like to know as well
peace
