You'll need the billet output shafts for those diffs. I read dat2kman's post as being for standard output shafts. I haven't bought them yet, I only asked for a price. If you need them they're all yours Quote Link to comment Share on other sites More sharing options...

d3c0y Posted July 3, 2016 Share Posted July 3, 2016 If it's a 4.11 and 2.0L car it will be an R160 and not from an STi. To my knowledge Subaru didn't use 4.11 R180s. The type of LSD center you want depends on what you are using the car for. All three will work and be better than an open diff especially on the street, but I would probably rate Mechanical, Torsen, SureTrak with mechanical being the best if you are going to the race track. Torsens only come in 3.5 ratio and are found in the GDG hatchback shape, but i think that is a bad ratio for any zed. 3.9 ratio Suretracks are the easiest to find and came in all GDB - GDC models excluding the STi Spec-C models which came with 3.9 ratio mechanical diffs. If you want an R180 LSD this is the easiest way to do it. Quote Link to comment Share on other sites More sharing options...
Cozza Posted July 3, 2016 Share Posted July 3, 2016 I got a 3.9:1 Torsen. Quote Link to comment Share on other sites More sharing options...
d3c0y Posted July 4, 2016 Share Posted July 4, 2016 I thought you had a SureTrak? For the record Suretraks have smooth carriers and mechanical are cast from memory. Quote Link to comment Share on other sites More sharing options...

Cozza Posted July 4, 2016 Share Posted July 4, 2016 just picked up R180 LSD with 4.1:1 ratio Good score, was that the one on Ozdat or you got a Subie one? The one recently for sale on Ozdat looked like a good deal. Quote Link to comment Share on other sites More sharing options...

Nah both Torsens, I've just been searching my phone for pics of my centres but don't seem to have any. From memory they are cast but can't be sure. I'll try to remember to get a couple pics next time I do a swap over. Quote Link to comment Share on other sites More sharing options...
