Tripping On Lsd

[FurryBarry]

Hey Kids,

I've scored a Cusco 2 way LSD which has gone into my R32.

Does anyone have advice on whether it is possible or advisable to use the stock rear centre to replace the open front diff?

As far as I know the stock LSD is a 2 way jobbie, and I'm worried that it'll cause understeering under brakes in tight corners.

I don't know if shimming the clutch packs loose would avoid this or if it's possible to alter the standard ramps.

Has anybody tried this?

Thanks in advance.

You are all beautiful.

Definately not possible. Rear diff is a 200mm crown wheel, front diff is something like 160mm.....the centre wouldn't even fit in the housing, let alone the front diff crown wheel.

Aren't the front diffs R180 units, so it probably won't fit.

[FurryBarry]

Yeah, manual says model number F160. Completely different critter, so stupid question on my behalf.

I do believe that there are such a thing as R160 mechanical LSDs kicking around in Dattos and Subaru WRXs. I wonder what sort of splining they use? Heh, would be funny to see the look on the face of wrexy drivers.

Basically I'm a tightarse and I'm trying to find a cheap way to get front LSD.

Anyone got a subie diff schematic?

Hmm the carriers in these pommy sube forum photos look the same as the gtr schematics

Non-STi rex's use an R160 with mechanical LSD as the rear diff (STi's use R180). The 'R' designation refers to the housing type, as does the 'F'. It _might_ be the case that an R160 centre fits an F160 housing, but frankly I'd be surprised if it was a 'bolt in' proposition.

Datto 1600's use an R160 diff in stock form although none came with an LSD (in Oz at least), and some have bolted in a rex centre, but usually an R180 is used because it's easy to fit and stronger. Some have even put in an R200.

There's probably a pretty good reason why Nissan didn't design the front with a LSD centre. So it's probably not a good idea.

Absolutely, with enough front torque they understeer more than enough

I had 2 and 4 wheels spinning, but never 3
