Stock LSD

Does anyone know what type of LSD is in the FTO (cone, viscous, clutch plate etc), my gpx has an LSD but maybe slipping, not as much when doing a burnout at the drags both wheels will spin with no problem but when I had it on the hoist I can get someone to hold one wheel and with some force could get the other wheel to spin, I work with many cars with LSDs and it takes a lot more force to make them slip.

Anyway does anyone know if there is a service kit for the factor LSD like a new set of clutch plates etc.

If its the stock item, then it should be the viscous type - and if there is a reco kit for it I'd be very interested to find out where to get it from & how much...

If it is a viscous type then I think its normal to have that much slip then, the ones that I played around at work are usually cone or plate type and are pretty tight and if they slip they are usually worn.

Thanks anyway Bennoz.

It's a helical LSD if thats helps any. I've found it does have a fair bit of slip in my car. compared to the other clutch pack diffs I've seen and driven. Still love it though.

Its better than not having one,

Helical is the way the gears are cut not the type of diff... please correct me if thats not what your talking about. Most modern road cars use helical gears in both the g'box & diff... track cars can have semi helical or straight cut for more hardcore applications.

Here's a pic of the final drive gear (which meshes with the diff crown wheel) in my mini - note the different between semi helical & fully helical.

same, I have never heard of a helical LSD, but RPW does a LSD that works with gears,

I'm not sure how it works, never seen one of these before.

Oh, okay sorry. Thanks for the pic Ben. Now I understand that.

From my experience with Quaife diffs in rally cars they are clutch pack - plate? diffs. The Cusco LSD RPW was selly was also a one way clutch plate diff wasn't it?

Cusco has 2 LSD's the RS which is the plate type and then the MZ which is the cone type, you should be able to get them in 1 , 1.5 and 2 way but I think RPW sells the 1 way as its better suited to front wheel drives.

ah ok, thanks bigpitty.

Not that I'm thinking of upgrading. I'm quite happy with the stock LSD.
