Yep, much more controllable when your sideways and steering it on the throttle. 
It basically stops all the power being transferred to the spinning wheel, as a normal diff would do.

Might as well just weld it up in that case. No point in destroying rare and expensive LSDs if your only objective is to d**k about.

especially as road car LSDs rarely lock up more than 20%, and break if you use them hard.


They're a waste of time in a low power car too.

Precisely. You've only got to look at them to know they are not going to take any abuse.

Its not just about Drifting though is it, having near equal Torque on both back wheels can be usefull, hence why the Police have them fitted, its got me out of trouble a few times in the Ice and Snow in the Forest in the past, ok its not 4x4 but having both rear wheels engaged rather than one just spinning hopelessly certain is a better option. 

[Kevin Wood]

Yes, there are occasions when they will help out with traction, and that's what they are designed to do. Then again, the traction control system will do a similar job, and that's probably why the LSD, which was standard on the Senator, got dropped on the Omega.

TC with an open diff has the advantage that it makes it less likely for inexperienced drivers to spin the car when they find the limits of adhesion, because an open diff provides a "safety net" of disabling torque to the outer wheel when the inner one loses traction. Then TC disables the engine, then re-enables it, then disables it....etc

Adverse weather aside, I think the only scenario when an LSD is nice to have, is nipping out of T junctions quickly or exiting roundabouts where the inside wheel letting go can stunt your progress if "pressing-on".

Yes, they're 'useful' for keeping the car sideways until you reach for second gear

Not necessarily, just stopping them from bogging down when the inside rear lifts.

...as if I'd be in the driving seat of a vehicle while progressing in a yawing fashion on the public roads.

Someone had to say it.   

[TheBoy]

Never having owned a car with one fitted I have to ask-just curious-are these things really worth the hassle of seeking out/cost of purchase/time and effort to swap for an ordinary diff?

Yes, definitely worthwhile, else it just spins up the lightly loaded rear tyre when pulling out of corners.

[BazaJT]

If they were standard on Senators as KW says then I take back what I said about not having a car fitted with one as I've had 3 "A"s and 2 "B"s just can't have noticed they had one.

Simply not trying hard enough, Mr Baza...

Obviously not TB,further training required methinks

[dave the builder]

the carlton/senny LSD required a special diff oil / additive
if un-serviced or left un-used for long periods the diff looses its LSD capability IIRC

Same as the LSD on the Omega, some of the Ex Plod Omegas that the went into Private hands got screwed up this way, even if they went into a Vx Dealer for Servicing.

worthy of a mention .just in case someone decides to retro-fit an lsd that's been sitting in storage since 1990
