Not sure if my Cup has an LSD

[skiptontweed]

I know the 172 Cup didnt come with an LSD from the factory (I think) but,

I have owned my Cup for 6 months and it never spins the inside wheel exiting a slow corner unless I REALLY provoke it. Also, the car doesnt suffer from much in the way of torque steer, even under hard acceleration in the wet.

Finally, when puling away carefully on wet grass recently my mate noticed that both wheels were spinning exactly the same and for exactly the same distance - a few meters.

Is this behaviour any different to anybody elses standard Cup?

Im trying to work out if the car has had an LSD fitted by a previous owner, there is no paperwork with the car suggesting its had anything fitted.

If I jack up one wheel and attempt to turn it will it be immediately obvious that it has an LSD?

you need to jack up both wheels, spin one and if the other wheel turns the same direction its an lsd

Park on pavement with grass verge.

One wheel on tarmac, one wheel on (preferably damp) grass.

Pull away - that'll tell you without doubt.

You say it will spin the inside wheel if provoked?

If so, you don't have an LSD.

The quaife will do the same as a std diff as if there is no traction at all to 1 wheel it doesnt 100% work.

Thats for a plate diff but doubt it has one.

Thanks, I'll try the one wheel on tarmac idea and see what happens.

By provoked I mean if Im cornering hard and unweight the inside wheel while accelerating hard in a low gear.
