What Bits This?

Thats the differential (the bit that makes the wheels go around) weather there is an LSD inside depends on model etc

ok thanks, how do I know if its a LSD?

its a uk car

Then unlikely to be an LSD unless someone has swapped it for an import one. UK cars never had them.

ok, thanks.

Is there really any benifit of having a LSD?

I dont do track driving or anything like that.

Nope none at all.

You've kind of hit the nail on the head: if you don't drive hard (-ish) then you are probably never going to feel the benefit of an LSD anyway. For track/quick road use, an LSD is a good thing to have, and most would say its essential.
Don't forget that there are many thousands of MX5s out there with no LSDs that all drive perfectly well and are probably loved by their owners.

cool, thanks for the info folks.

I will just leave as is and save my pennies for something else.
