Is it worth it to swap in an LSD from an S model into an automatic L? I'm researching how to swap the rear drums for discs and it looks like I need to replace the rear subframe, so I figured that would be a good time to upgrade to LSD.
I want it primarily for snow traction, specifically for getting out of jams so I guess that is not going to be worth it for me. The car is never going to be fast so I don't need it for performance. That how-to is very informative but are you sure the process is similar for an SF? I was told I needed to change out the rear subframe (I think you guys call it a crossmember?) in order to change to disk brakes. That write-up doesn't mention that so I'm wondering if it is different or if I got bad information.
I did a drum to disc conversion on an older Impreza, and know my way around Subarus enough to be surprised that there would be a need to change the subframe. It might be FASTER if you have an entire back end to put in the car, but not needed.
