Default Fioroni Aluminium Diff case-Anyone used it before?

Hi there,
I would like to find out if anyone used the fioroni aluminium diff cases.

I have an mp9 for many years now and i have bought another tki4 and since its first build i ve used the fioroni center diff case.

The car from the first day was very twichy with tons of steering at a point that i could not drive it.

I though ok is the tki4 geometry so i changed everything to tki3 geometry.

I had also the ms high roll centre front tower and i thought i need to change that also to stock as it might affect twichiness.

The car still was very responsive and twichy. So i thought i need to go to 16 caster.

I installed the 16 caster waiting for the big change and the car was very twichy again.

My friend has a tki4 with the tki3 geometry and 13 caster and the car is almost the same like mine and his car is very calm with much less steering.

Also i have a tki3 that is again a very calm car.

So the only different item that is left is the fioroni center diff case.

The case uses pins to hold the spider gear and also it seems that it can hold more oil inside.

Therefore i thought i might need to change my front oil to higher viscocity to calm the car down? or is it something else that i can not think as of now.

My question is has anyone used one before? Any comments will be really appreciated.

Thank you.

I have one in the center and understood the only difference was that it ran a bit cooler. Other than that I haven't noticed it being twitchy.

I believe I used one, but they are really heavy and leaked terribly. Looks nice though...

Might have got a bad one. But compare weight, it's usually never a good idea to add weight in the drive train.

I believe I used one in the center... I used it on a HB, and there it was a pretty big difference in weight, over 20 gram and that is a lot of weight especially with that diameter.

Yes it's on my Mp9 tki4. I've had the screws back out as I was warming up at DNC, but since then no problems.
