Open Diff. & VLSD - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I am thinking about getting a VLSD for my 240SX to correct the understeer I get at low speed turns.

How different is the handling characteristics of a open differential 240 and one equipped with VLSD?
Is rear tire grip improved?
What changes can I expect?

Thanks you in advanced for the help!

the handling should be better since both tires will have equal power going to them. this will make your car easier to control in winter and other inclimate weather. also, i dont believe that a new diff will cure your understeer. in my s14 i have always gotten massive oversteer when going through low speed corners. to cure your understeer id look more towards suspension upgrades.

would you think a Stage 2 clutch along with a VLSD would make a faster off the green time or not?(and engine mods as well)

yes it will make a difference... from what i've seen, aftermarket clutches catch much better than stock ones. also, with lsd, both the tires "grab" instead of just one.

Without getting too involved, a limited slip diff can function in different ways.  In terms of the VLSD, it functions almost like an open diff in normal operation making it very streetable, but will only transfer power once one wheel begins to spin and heat the viscous fluid enough to engage the other axle.  It's reative traction.

Would this "VLSD" in the S14 the same as the "Active LSD" in the ECR-33?

I don't think so (that it's the same as "active" lsd) -- from what I understand, Active LSD uses sensors to detect slip, and lock the differential accordingly, as found on the EVO VII AWD system and apparently on the GTR AWD system.
I can't say exactly how this works (I don't have a clue) but VLSDs, to the extent that I understand them, are passive.
