LSD Kit - Yes or No?!

Good afternoon

Does anyone have some kind of experience, or have you tried these "diffs"?
It seems to me that will cause premature wear on the differential crown ...
Has anyone installed this yet? What feedback do they have?


Thank you

What are you going to use it for?

Road?
Trackdays?
Racing?
Rallying?

Are you prepared for regular servicing or do you want fit and forget?

Hi

Track use.
I'm aware there will be more iron filings in the oil than usual.
Maybe they change the oil more often between trackdays.
But the doubt is, has anyone tested this?

I think the perceived wisdom will be you are better off with a plate diff and that you’ll need to be prepared for more regular servicing.

As Dave said the one you linked to looked about half the price you’d expect to pay for a mechanical diff which puts it into the too good to be true category.

Do you know any one using one?

Hello
I just have an example of a SSGTI (Suziki Swift GTI) that uses this type of "LSD" for a few years, and never had problems. But we know that Japanese stuff is better than French (I mean the boxes) ...
My question was if someone with a 106 already tested this solution and had problems.

According to the website there are at least two 106 owners using the product (see references page). I’d suggest you contact them.

As this is a Serbian product it’s not in broad use in the UK. Most people here use(d) Quaife, Gripper or TransX

From technical point of view, this can't work, at least not as a true limited slip diff anyway. There are not enough friction points, only two on each side, and a true LSD has at least four (depends on how the plates are set up).

This is a diagram of a true LSD:

You can see that it has many internally and externally toothed plates, and the "mod" that you posted actually has none of these plates. It only relies on the friction between the planetary gears and this friction plate with some springs.
I have seen this type of mod 15 years ago. Some local drag racers made it them selves for FWD cars.

If this would be that good as this site says, than A LOT of people would be doing it and there would be less diffs like Gripper or Quaiffe in cars.

And to add a little more. A lot of the MA gearboxes that I have opened have the planetary gears already chipped and broken. Adding this mod to a standard diff will only add more stress to it which means it will get broken sooner.

My advice to you would be, save the money and buy a proper diff.

Hello


Thank you very much for the opinion, I think the same. I just wanted to demystify this "LSD" in MA boxes.
I think I'm going to save money, and I'm going to add a ecumaster det 3 and fine ... and I leave the LSD "problem" for later.
