This is a light LSD for vehicule with power less than 200 bhp.

The extra torque on the blocked wheel is 3mkg, as write to me the distributor.

I'm going to test this solution , in may certainly, on the new gearbox I would install on the Lancia .

I'write you comment on this installation and driveability.

hi does this diff have cones in it?

I have just had a similar setup made but it uses the springs to preload cones as per Borg Warner type LSD's. Under high input torque the cones try to push against their seats in the casing, effectively trying to lock the output shafts of the diff. Under low input torque the side gears reduce the amount of side thrust on these cones, so they can slip and act like more like an open diff.

here are some pics:

to 75coupe, Have you test this solution on your car?

On the net, I read this solution may damage seriously the gearbox, because of "inhabituel" usage of the  gearing and an accelerated wear of the teeth.

Hi I have not tested this yet, but the person who did it successfully ran this setup in a highly modified Fiat X1/9 Prototipo replica running a Beta 2 litre engine and gearbox.

I will update once I have tested it.

Dear All

I have now tested the diff on the road and it works very well. It has eliminated virtually all inside wheel spin when pulling out of tight corners - I can now use full throttle in 1st gear out of a junction, whereas before it would just turn the inside tyre into smoke.

As for how long it will last is anyone's guess, but as with al mods you had to expect greater wear & tear!

Will update once tested on the track....

Ok do you think this solution may be useful in rally ?

I think Yes.... but if the gearbox break It will hurt....

Have you test it on track ?

Hi Archie,

I will be testing the diff again soon with new Guy Croft 190BHP engine, so will let you know. I have a hillclimb to do end of February, so will update then.

This subject has been in the forefront of my mind again and I found this thread.

Is there enough testing to give us a longterm type update?
