Rear Diff.

[dencon]

Recently bought a rolling shell to build a new hillclimb car, and find it has a Viscous Lsd rear diff. Is this going to be any good for my purpose, or am I going to get a lot of wheel spin out of corners.
My existing RB has a very tight clonking rear diff but never gives any single wheel spin. Anyone used a Viscous diff?.

Pulsar's/sunny gtir come as standard with viscous diff's in the rear end and the center (the one in the gearbox) clutch type Lsd's were an option, as long as the diff is ok you should be fine. (keep your rb diff though if you are sure it's a clutch type lsd)

Both viscous and clutch type lsd do wear out btw.

If you want more info just ask.

Thanks for imfo,is special oil needed for this diff to get its grip?, and is there any adjustment provided?, I have a spare plate diff that came off my RB nismo
but it needs an overaul. I know you do gearboxes but do you do diffs as well.

fully synthetic for a clutch type lsd (silkolene syntrans 5 or similar 75w/80 or 90)

and for a viscous just use cheap comma 75/80 gl4/5

the nismo lsd MUST use fully synthetic or it will wear out very quickly.

As for nismo diff refurb's where would you get the part's to rebuild them? and what are the spec's to build too? if i have these i can do it.
