After going with a 6 speed manual, CD009 in my case, I found out real quick that the 3.91 auto ratio does not work well with it whatsoever. I researched and came up with the Driftmotion 3.58 rebuild kit that fits the factory carrier case and provides a dramatic improvement by lengthening the gearing.
I put approximately 5K on the setup but always wanted to go even lower, 3.26, so I'm in the midst of that project now.

Long story short, this 3.58 Driftmotion LSD is available as a direct bolt in for anybody who might be interested. $800 is what I'm looking for, which basically equals getting the LSD carrier for free after the rebuild kit and setup cost. Give me a shout if interested.
