I've had my eunos S-Special for a few weeks now and love it.

Its got a LSD, i understand the principle, but really whats the advantage on the roads for normal and a bit spirited driving?

In "normal" & spirited driving i.e. normal driving but a bit faster, on dry roads there is no advantage to an LSD at all. Most people probably don't know they have one and wouldn't miss it if they didn't.
The advantages they give you are basically in traction (without LSD power will be lost on a spinning rear wheel) and in control of the back end when rear traction is lost i.e. when oversteering as it's easier to fully control the slide when you have control over both rear wheels with the throttle (again, without LSD one wheel will spin but the other will be trying to match road speed so it will tend to snap back out of oversteer).

How do you tell if you have a LSD?

I'm assuming with the wheels off the ground they'll both spin the same way? I tried this recently when I had my car up on the jack, both wheels spun the same way, although the other wheel spun noticabley slower. Also my handbrake was only working on one wheel at the time, so with the handbrake on I started the engine and the free wheel spun forwards. I assume from this that if I'm lucky its probabley got a viscous diff that might still work (my car's a 92 Eunos)? or perhaps I've just got it all wrong!

The fun way is to do an emergency start.

Smoking 11's, you have LSD. Just one line and you don't (or you have a worn out one).

Park with one rear wheel in soft sand and the other on tarmac. If you have LSD you will get out if you are careful. If you don't you'll be stuck there. I've seen it in action!

That's a simple yet great explanation.
