Cannonball89 Posted November 5, 2011 Share Posted November 5, 2011 I am going to put some sort of LSD in my 240z over this winter. My first choice is the Subaru STI R180, with John Coffey's side axles. I figure that swap will cost between $800 and $1000 ($500 for the side axles, and anywhere from $300-$500 for the differential itself). While browsing Z Specialties site today I saw that they now sell and LSD conversion kit for the open R180, for $350. This would probably be a cheaper solution, even though I would probably pay someone to install it into my differential (the instructions look somewhat intimidating). What I don't know is if this would be nearly as good as an STI LSD. I haven't found any reviews of it, and the Z Specialties site doesn't really tell you what kind of LSD it is, other than a statement saying there are "no clutch discs to wear out" so it is obviously not a clutch LSD. The picture looks like one of the Phantom Grip unit's I have seen. I'm sure some of you can I.D. it from the picture below. So what are your thoughts on this? Is it worth $350, or should I just look around for an STI Diff and get on the side axle group buy list.

duragg Posted November 5, 2011 Share Posted November 5, 2011 STI diffs are rare and spendy right now. Why not pop a Powerbrute clsd into your 180? Quote Link to comment Share on other sites More sharing options...
madkaw Posted November 5, 2011 Share Posted November 5, 2011 I found one on the Subby forums for 350$ with 60K miles(so he said), but it looked new. Maybe I just got lucky. Quote Link to comment Share on other sites More sharing options...
duragg Posted November 6, 2011 Share Posted November 6, 2011 Was that recently? I've been looking, but they at least go fast. A few "R180 LSD" I found were actually earlier R160s. What ratio did you get? How do you find the difference driving? Quote Link to comment Share on other sites More sharing options...
madkaw Posted November 6, 2011 Share Posted November 6, 2011 It was in the last few months. I went on the NASIO site and it was sitting there in the classifieds.I couldn't believe how clean it was-inside and out!~ It was a 3.90 ratio. I didn't care about ratio that much because later on I can just swap out, trade, buy another Subby LSD with a different ration. This is a much better deal than being stuck with 3.7 in the r200. I don't know how to change gearing or install a LSD unit---but I can swap out a diff!!!! Quote Link to comment Share on other sites More sharing options...
duragg Posted November 6, 2011 Share Posted November 6, 2011 I joined that NASIOC forum and have been watching, but I must have slept in that day! Good catch... Quote Link to comment Share on other sites More sharing options...
Cannonball89 Posted November 6, 2011 Author Share Posted November 6, 2011 Yea I don't think phantom grip is the way I want to go... there might not be any clutch disks to wear out... but instead your wearing the spider gears and the case... not an improvment in my eyes. I will look into powerbrute, cusco, and kaaz, but I think a factory suburu LSD is going to be better for a street car. I don't want a 3.90 diff, with my turbo it will be faster with the 3.54 diff, and I want a clutch over a helical, so as far as I know I am limited to the 2006 STI diff. I haven't seen what the newer 2009-2011 cars have yet, but I think 2006 is the only year that will work. Quote Link to comment Share on other sites More sharing options...
