Which is better CLSD or VLSD?

yes if its R160 diff then it can be done by taking out the LSD centre and put it in L series/Liberty Diff centre. Make sure you use the bearing housings from the wrx otherwise the bearings wont match the l series housing (where the shafts are).

i want a lsd, whats the easy way to convert will a vlsd from a rs turbo or such bolt straight into a brumby

it will bolt in yes, but it will likely be the wrong ratio. the ratio must match the final drive of your gearbox. if you get an imported RS turbo diff it will probably be 4.111. It is possible to swap the VLSD part of it into your existing diff and use your existing diff ratios. search for the guide on how to do this, it's been covered a few times (at least once by me

)

All aus RS turbos had a 3.545 rear end. the rear diff isn't 3.9

just to make this clear for everyone....they do have 3.9 ratio gearboxes but the rear output is stepped down to 3.545. This means the VLSD from an aussie RS can basically not be used with any other suby gearbox unless you re-ratio it.

Viscous hubs are not a serious limited slip device , they rely on a speed difference to limit the differential action if you know what I mean .
Manufacturers like them because they are quiet and "soft" on the drive line unlike any mechanical LSD .

Saulsbry (Sp ?) or clutch plate LSD's if you like are a load sensative device meaning they can load up and not spin unlike the viscous whimp . They work by the spider legs moving in beveled grooves in the hemispheres casing and load the clutch plates up even more that the static pre load does .

BTW you don't "shim up" a plate LSD you add extra plates and belville washers to increase the friction area and preload .

You won't find a front or rear Viscous diff in a serious rally car , maybe the center one in some Subies but not the others . Front or rear viscous ones slip too much , cook their fluid and then don't work at all .
