I've just gone through pages and pages regarding the OEM LSD and the only thing I've really gathered is that it doesn't compare to the quaife LSD. What I need help with is whether or not to get an OEM LSD or stick with the open diff. I'm getting a GSR swap done right now and the guy has two trannies for me to choose from. A stock GSR tranny or a b16 with LSD and same final drive as a ITR...something like that. He said I can get the LSD equipped tranny for $300 more. I mostly drag and occasionally push my car around the twisties. Would it be worth my while to get the LSD equipped tranny. I read that the OEM LSD doesn't like slicks and being dragged? Help me decide H-T! Thanks!
