Wild,
I don't know anyone in the UK with the calmini 3 inch kit who hasn't exploded an ally 3rd member...
Not trying to argue with you, just a point of view is all....
cheers

Naww, you just want to pick a fight

OK, I will agree that some of the UK guys have had
more than their fair share of nuked front thirds and
5.83s too, gets kind of spendy.
Here is what I have done to help prevent broken bits
1. replace stock bolts with longer ones, I wish I had
recorded the length that I used in the diff area of the
housing, if that bolt is too long it will hit the gears.
2. lock-tite, red stuff, if those bolts get loose things
move around and stuff breaks, I also filled the open
cavity under the side mount with weld, made it solid
to prevent bolts loosening and breaking the housing.
3. last is to reinforce the snout with 2 crescent shaped
pieces of 100 thou aluminum plate, no pic sorry, but it
solidifys the 2 bolt mount ear on the snout to the snout
it's self, helping to prevent cracking it open like an egg
OR you could do somthing like this

One of our South American Zuki Brothers came up with
this solution to nuked aluminum diffs.
Enjoy
